How to extract zinc from batteries

Homemade device for combating corrosion from a regular salt battery - Finishing

The master showed how to make a very simple but at the same time very effective device for combating corrosion on a car. The device is so simple that even a child can make it. To make it, we will need ordinary salt batteries, and it should be written on them that these are salt batteries. These are usually the cheapest batteries.

Alkaline batteries are not suitable for us, since their body is not made of zinc, but these ones have a body made of 99.9 percent pure zinc.

We take one battery and strip its body of the insulating film. To do this, simply cut the film. You will need a piece of wire. We wrap this wire around the battery, but to ensure that the wire holds well, we wrap it with a regular rubber band.

We attach an electric clothespin to the other end. Then you will need regular cotton pads. We take one disk, wrap it around the battery and secure it with an elastic band. The result was a device to protect cars from metal corrosion.

Next, we take regular soldering acid orthophosphoric acid and moisten the cotton wool that we attached to the batteries. Well, that's all guys, the device is ready. All that remains is to connect it to the car battery.

How to remove rust and galvanize a car body with a battery

We connect the electrical clothespin of the device to the positive terminal of the battery and now we can remove rust, not just remove it, but even galvanize the metal.

A typical source of corrosion on a car's wheel arch. We won’t even clean this rust, we will immediately treat this place with the device. We simply press the moistened cotton wool to the place of corrosion, the rust itself will go away, and the metal that was rusty will be covered with a layer of zinc.

You just need to press and hold for a few minutes. The zinc from the battery body will transfer to the metal on the car body and this place will no longer rust in the future.

You can see how the rust is almost all gone. After galvanizing, there was no trace of rust left, only a small thin layer of zinc appeared. This is clearly visible - it has a silver color.

Neutralize the acid

After the rusty area has been treated with a manual galvanizer, the effect of the acid must be neutralized. For this we need regular baking soda.

Pour a little into a glass, dilute with water and the composition for neutralizing the action of the acid is ready. We simply soak a cotton pad in this solution and treat the area that we have galvanized.

Look how it sizzles - this is the acid we used as an electrolyte being neutralized.

Varnish painting

Budget for painting this place with regular nail polish. Choose the varnish to match the color of your car. There will be the cheapest pencil for touching up chips on a car.

This was such a budget renovation. From a distance of two meters this place is almost invisible, and most importantly, it will not rust anymore.

If you liked my method of fighting rust, please like it.

Second life of batteries

Everyone knows that batteries charge energy for a variety of electronic gadgets, while the agricultural inclinations of alkaline batteries are a fact little known to the general public.

The first wave of battery recycling occurred at the start of the new millennium. The massive passion for gardening, acquired in the 90s of the last century, pushed amateur gardeners to various experiments.

It happened that used batteries were buried in a personal plot, expecting a bumper harvest of apples or other garden crops.

From myths to reality

Having gone through a boom in popularity, miniature autonomous energy sources have fallen out of favor. As it turns out, batteries contain not only a couple of volts of DC voltage, but also toxic elements: lead, cadmium and mercury. Another interest, especially in alkaline batteries, arose with the prospect of using them as mineral fertilizers.

Of course, it is no longer proposed to fertilize the soil entirely with a battery, as was done at the dawn of the 2000s. The essence of the idea is to isolate zinc, as well as manganese, from metal cylinders of AA, AAA and other sizes. In addition, batteries are full of graphite and iron, elements that are also recyclable.

Alkaline battery device

Practice is the only way to test theoretical research. Therefore, the suitability of an alkaline battery can be checked by disassembling its device into components:

• anode – high frequency zinc in powder form;

• cathode mass – manganese dioxide (80%), graphite (10%), potassium hydroxide (10%);

• positive current conductor – nickel-plated steel housing;

• separator – cellophane or polymer;

• negative down conductor – brass.

As you can see, a regular alkaline battery acts as a source of ferrous and non-ferrous scrap metal, as well as a component of fertilizers.

And if the weight fraction of metals in the battery is relatively small, then 40 grams of manganese dioxide per alkaline current source, size D, is quite a decent amount. For comparison, a similar salt element can only hold 28 grams of MnO2.

Thus, the prospect of using the zinc-manganese element to fertilize agricultural crops is not a page of ancient Greek mythology, but a very real fact.

Sorting batteries manually

Transformation technology

The procedure for converting an alkaline battery into a set of useful elements is quite simple and can be implemented at home, especially on an industrial scale. The whole process contains two stages:

1. Splitting up. The element simply needs to be broken down into small components.
2. Separation. It is required to separate steel, copper alloy and manganese-zinc powder mixture.

Crushing batteries

Battery crushing in production is carried out in specialized drums with hammers. The separation of steel particles is carried out under the action of magnets, through which the crushed composition is passed. The extraction of shoals from the powder is carried out using eddy currents.

As a result we have:

• zinc and manganese dioxide powder.

In fact, everything is ready to fertilize agricultural crops. In addition, by handling large quantities of used batteries, hundreds of kilograms of recycled steel and brass can be collected. The prospect, of course, is more suitable for production scales. However, you can make a mini crusher with a separator on your own plot, just a small room and skillful hands.

Zinc powder

What and how to fertilize

Corn has the main need for zinc and manganese. This agricultural crop is especially responsive to fertilizing during the following growing periods:

• the beginning of the appearance of leaves, already 3 - 4 green petals - a signal to the gardener;

During the growing season, corn has been found to absorb up to 80 grams of manganese and five times more zinc per hectare of crops. Therefore, if the soil is deficient in microelements, batteries will come in handy. This problem is especially relevant for neutral or alkaline soil.

Lack of manganese in latent form in corn is typical for crops growing on soils with a neutral, alkaline reaction. The addition of nitrogen fertilizers containing Mn helps increase yields by 10%.

You can eliminate the need for zinc by spraying corn shoots with a 25% solution of zinc sulfate. You can verify the need for the procedure by noticing light stripes on the leaves of plants. This is a reaction to zinc deficiency.

Alternatively, used batteries can be replaced with Opticoat, a product used to inlay corn seeds with manganese and zinc. In particular, the Finns, who, together with the North Americans, intensively use the recycling of batteries for fertilizers, combine phosphorus with the resulting microelements: Mn, Zn. This promotes field germination of crops.

Use of zinc and manganese sulfates

However, the demand for manganese and zinc is not limited to corn alone. Another effective fertilizer is the sulfates of these elements. In particular, manganese sulfate is used for the following crops:

• wheat, winter or spring varieties;

Zinc fertilizers are effective on carbonate chernozems and sandy soils. They prevent diseases of fruit trees: apple, cherry, walnut and others, as well as corn.

As practice shows, alkaline batteries are far from being thrown into the trash bin. Once out of use, they can still provide benefits by energizing agricultural crops.

312 batteries

The first thing that catches your eye when you see the complex is the bright design of the equipment in blue, orange and silver tones. Despite the appearance of one solid mechanism, it consists of three parts. The other two parts, where raw materials are divided into types, are domestic. We assembled all three parts into a single production line. The technology was developed by scientists and specialists from BNTU.

Near the complex there are blue barrels with batteries prepared for processing. They are first sorted by hand by repairman Yuriy Grintsevich in a separate area. Among the wastes, there are also mercury-containing and cadmium-containing wastes.

You won’t immediately understand what to throw where. But I got used to it pretty quickly. For safety, I wear gloves. Selected batteries are stored in special containers made of thick plastic. From one of them, waste was poured into the shredder hopper and the system was turned on. The process has begun. It has a special sieve where the crushed material is divided into small and larger fractions, which then enter two magnetic separators. These look like ordinary metal boxes.

In one, iron extracted from batteries accumulates, in the other, zinc with organic compounds, remains of paper, pieces of fabric that served to separate the layers in the batteries. This is where the process ends. The resulting recyclable materials will be taken by the enterprises interested in them. Zinc is a non-ferrous metal and is also in demand by domestic manufacturers.

If it is not suitable in this form, we will install an additional separator that will separate pure zinc. Another component is also extracted - a manganese-graphite mixture. BNTU employees are now studying how suitable it is for use in metallurgy. Until now, manganese was purchased abroad. If the answer is positive, we will receive our own, domestic one. Cadmium and mercury-containing substances are also still found, but their share is small. In the future we plan to export them abroad for neutralization.

There are already agreements with processing enterprises. In addition, the work does not use any chemical or temperature processes, but only mechanical action. We tested the line for environmental safety. Everything is fine. A package of documents is currently being prepared for registration of this object in the register of the Ministry of Natural Resources.

One of the stages will be taking measurements for harmfulness. If necessary, we will install additional hoods. According to Igor Gorbachev, the storage facility now contains more than 70 tons of waste batteries, and their number is increasing. In just 6 months of this year, more than 28 tons were collected.

Of these, in Minsk - 16 tons, more than 15 tons - from the population. For comparison: over the same period, they collected 2 tons of waste batteries. The capacity of the new facility is tons per year. This will close the issue of recycling batteries not only in the capital, but throughout the republic for the next 5 years.

However, if necessary, the capacity of the facility can be doubled by installing additional equipment. There are plans to place more in the city by the end of the year. We created three new models because the old ones looked like ordinary trash cans, and people habitually threw household garbage there.

The new containers are bright green and clearly marked, so you can’t confuse them with anything else. Photo by Tamara Khamitsevich. Our projects.

Types of batteries by size and chemical composition: CHIP cheat sheet

The battery, which is intended for a hearing aid, operates in pulsation mode, which is a rather complex system: if there are no sound vibrations on the device, then the power consumption is low, and accordingly, the waves of electric current that pass through the battery are minimal.

But when sound waves enter the hearing aid, for example when starting a conversation, the hearing aid needs to amplify the sound waves, and accordingly, energy consumption increases significantly. This will increase the electric current that passes through the battery. If the battery supports this power, the device works normally.

If the battery cannot provide this mode, then the hearing device will experience abnormalities in the form of electrical signals, thus distorting the sound in the device. In addition, the battery must provide the hearing aid with a stable electrical voltage for a long time, that is, it must have high electrical power.

Otherwise, if the battery voltage gradually decreases, this leads to deterioration in the performance of the device, which reduces its effectiveness for the consumer.

In one, iron extracted from batteries accumulates, in the other, zinc with organic compounds (paper residues, particles.

The device of a finger-type, round, crown, telephone battery

Do you often want to know what's inside the battery? What does it consist of? What is the battery structure? And that's why a lot of people are starting to take it apart. But upon opening the battery, they find some strange elements. The information presented here will be understandable even for children. The article will bring clarity and try to answer your questions.

What's inside the battery?

The structure of four types of power supplies will be discussed below. Essentially, the principle of operation is the same, but these energy storage devices consist of different components.

Composition of a AA battery

The battery contains the following elements:

1. The cathode is the negative pole
2. The liner serves as a kind of gasket
3. Diaphragm
4. Case
5. Electrolyte is a liquid that causes a chemical reaction.
6. Rod made of coal
7. Fastening washer
8. Anode or positive pole

This is approximately what the composition of finger batteries looks like. But sometimes their structure is different. For example, only a coal rod, special dark powder and metal elements can be used in the structure.

Round battery device

The flattened battery has a peculiar shape. Here is the structure of a battery in cross-section:

1. Positive end
2. Negative pole
3. Porous gasket soaked in electrolyte
4. Mercury oxide
5. Zn powder

The battery design may be slightly different:

Energy Cell Details:

If this element is heated too much, it can easily explode under the pressure of internal gas. So now you can contemplate what's inside the battery.

Phone battery device

The principle of a mobile phone battery:

1. Positive and negative pole
2. Anode glass
3. Cathode contact
4. Separator
5. Seal
6. Safety valve
7. Insulator
8. Cap
9. Partition
10. Aluminum or other housing

Thus, the design of a mobile phone battery is a little more complicated than a conventional salt power source.

What does a Krona battery consist of?

This energy source is designed as follows. The plus and minus contacts are located opposite each other at the top of the battery. Below them is a plastic base. From the negative contact there is a plate going to the negative pole. And there it is tightly attached. The battery composition is similar to the above power sources.

Inside the metal rectangular cup there are 6 rounded flattened rectangles. Each of which is a separate battery. Size of these elements: Long: 2.2 cm; Width 1.5 cm; Height: 0.5 cm. Each barrel has a charge of 1.5 volts. They are separated from each other by special plates. But they are still connected to each other in the middle. Such a battery device is cost-effective!

What's inside the battery?

Here's a cutaway view of the battery itself. Sometimes she can be like that.

But usually you can see that the crown is made of the same type as in the pictures below.

Its structure is quite simple:

1. 2 contacts “+” and “-”.
2. Metal body.
3. Bottom and top plates made of plastic.
4. Six 1.5 volt rectangles connected to each other.
5. Electrolyte.
6. Carbon rod
7. Inner film.
8. Insulating plates.
9. The battery device also includes a wrapper.

Battery case and what is it made of?

Such a part of the battery as the case plays a very significant role. Essentially, it holds all its contents and prevents parts from falling apart in different directions.

Which batteries have a zinc body?

Many people are interested in this issue and this is not without reason. Zinc can be used for a variety of experiments. Or you can simply sell it. Salt power supplies have a zinc body. Usually they have an inscription on them that they are salt.

Recently, there have been batteries whose surface is made of iron or tin. This is due to what is inside the energy sources. For increased strength and protection, this type of casing is required.

What does the AA battery body consist of?

It has a simple structure and consists of several parts:

• Upper
• Lower
• Lateral oval
• Marking

But by housing, sometimes people mean the compartment where the batteries are inserted. For example, something like this:

xbox 360 battery case

It looks something like this:

You can make a battery case with your own hands. But this takes time. The video below shows how this can be done using improvised means.

Approximate chemical composition of all batteries

Each type of energy storage device contains different chemical elements. Here are the chemical elements found in energy sources:

1. Nickel
2. Cadmium
3. Lead
4. Mercury is now rarely used.
5. Lithium
6. Zinc
7. Manganese
8. Aluminum
9. Iron

Thus, the composition of the batteries looks something like this! But the structure of an energy element cannot include all these substances at once.

As a result, what batteries are made of is now clear.

Battery Factory

There are 5 best battery manufacturers in Russia.

Space

It has been producing energy sources in Russia since 1993. It has 35 factories both at home and abroad. Namely, there are factories in China. In retail outlets you can find batteries from this company under the name “Kosmos Premium” and “Cosmos”. This brand is widely known and has its dealers in different countries. Every year the company makes up to one hundred million sales of its power supplies.

This battery plant has long proven itself on the market on the positive side. The company has received various awards for its work many times.

Photon

A similar company began to deal with energy sources in 2011 and has already managed to become a leader. The company's success is due to quality products. The battery device from this company has excellent characteristics.

Batteries from this company have been tested and it turned out that they last quite a long time and are cheaper, for example, than Duracell. The Photon company produces salt power supplies.

Liotech

This battery factory was opened jointly with the Chinese. It produces lithium-ion battery cells. The factory is located near the city of Novosibirsk. The production area is very huge; it occupies 4 hectares.

Thus, this plant proves to everyone that a large competitive production of galvanic cells can operate in Russia. In addition, they improve the design of galvanic cells.

Energy

This company is located in the city of Yelets. The Ministry of Defense cooperates with it. And this gives reason to think that this is a truly reliable manufacturer. In 2011, special workshops were launched for the production of lithium-ion polymer power supplies. The production of AA batteries and accumulators is mainly carried out here.

CCK

This company has been operating since 1993 and produces lead batteries of the 4th and 5th generations. In addition, the plant is working to increase the capacity of energy cells and develop new materials. All products from this company last a long time.

The battery produced by this factory has a large number of discharge-charge cycles. This means that such a battery will last quite a long time. And you don’t have to change it every 2-3 months.

How are batteries made?

Battery production begins with cutting steel plates into oval parts. Next, it is rolled into a metal tube. Which will then be called the body. Chemical components such as graphite, silver catalyst, manganese dioxide, barium sulfate, zinc, thickener, potassium hydroxide are placed in it. The battery design is not always simple.

Next, the press rolls the cathode chemicals into granules. After this, a groove is applied to the body in order to simplify sealing. Then sealant is applied to the negative pole. In parallel with this, perforated paper is being cut on another machine. Apply glue near the negative pole. While the body moves along the conveyor, the glue dries.

Then potassium hydroxide or electrolyte is injected. Next, zinc helium is injected into the anode cavity. Zinc gives helium its silvery white color. A welding machine welds 4-centimeter nails to the battery cover. The charge will accumulate there before being discharged. Then the negative pole closes. Then all the edges are bent, and the energy element becomes similar to itself.

A special electronic machine checks each battery for defects and the presence of a charge of 1.5 volts. All that remains is to make a control touch and glue the sticker. Once this is done, each power source will have to go through the oven. The temperature in such a device is 198 degrees, and they will only be there for 3 seconds. This is necessary for the sticker to adhere well.

Battery production equipment

Various automated machines are used as installations for creating batteries. The company LIK and many others manufacture special machines. Often the battery design is improved and changed.

In essence, an automated line is being built, consisting of several machines. After all, you need to create a hollow cylinder, perform pressing, apply glue, add the necessary chemical elements, create and stick a sticker, and then also expose the battery to heat.

Here is an approximate composition of the line:

• Vibration machine
• Machine for creating a body, machine for an inverted body
• Automatic flow division into sleeves
• Paper handling machine
• Collecting machine
• Squeeze machine
• Ribbon
• Gateway
• Plate

Each company produces the lines differently and therefore the composition may differ markedly.

Why you shouldn't throw batteries in the trash - true or false

You've probably heard a warning from your friends that you shouldn't throw away used batteries anywhere.

Is this true or is it just a myth among environmentalists? Let's look at two points of view on this problem.

How can an ordinary battery harm humans and the environment, especially if it has already exhausted its lifespan? Why do people sort garbage and what to do with such household waste?

TV remote controls or old electronic alarm clocks contain the well-known finger or little finger batteries. Many of them have the symbol of a crossed out trash container.

It means that you should not throw this battery into a regular trash bin. This is the manufacturer's official warning.

To understand why, you need to understand how these devices work.

Each such product has two electrodes:

The electrodes are immersed in a liquid that conducts electricity—an electrolyte. This electrolyte may be dry, but the essence does not change.

The anode material oxidizes when interacting with the electrolyte. Electrons are released and accumulate at the cathode.

The chemical reaction of oxidation reduction creates a directed flow of electrons from one electrode to another. This is the electric current that is needed to operate the remote control, alarm clock, or even a Tesla car.

Dangerous and toxic substances

At the same time, depending on its type, many elements are hidden under the battery case: lithium, lead, cadmium, mercury, nickel, zinc, manganese.

Lithium, zinc and manganese are relatively safe. As for zinc, its content in small power sources is even greater than in the ore from which it is mined.

But mercury is an extremely dangerous substance that causes poisoning.

Cadmium is a carcinogen that settles in the human kidneys, liver and thyroid gland. It affects the functioning of every organ in the body.

Lead directly affects reproductive health.

True, modern models do not have such a number of toxic components. In phones, smartphones, etc. Nowadays, lithium-ion batteries are mostly used. It is not they that pose the danger, but nickel-cadmium ones.

It turns out that each battery contains a little poison. What happens to this poison after the food source ends up in the trash?

There are two ways:

If a battery is burned, all toxic substances and dioxides will immediately end up in the atmosphere. You need to burn it wisely, at a temperature of 1200 degrees, using special cleaning equipment.

It costs about 800 million euros to build such a plant. Therefore, they are rarely found anywhere.

In a landfill, it takes about 100 years for a battery to completely decompose. In fact, not a single power source produced in the world has been subjected to one hundred percent decomposition. But for the top layer to collapse from corrosion, sometimes it takes only 6-7 weeks.

After which, metals begin to poison the soil, groundwater, and reservoirs that we use for fishing and drinking water supply.

According to environmentalists, one single AA battery can contaminate approximately 20 m2 of soil or 400 liters of drinking water.

And on this soil fruits and vegetables can be grown in the future. Moreover, contact between even a very discharged battery and foil from a chocolate bar can cause heating.

That's why large landfills are burning one after another. It is not necessary to set them on fire on purpose.

Disposal of energy-saving lamps

The same pollution occurs if you throw away a smartphone battery, an energy-saving or fluorescent light bulb.

Of course, such light bulbs save money, but that’s definitely not the environment.

By the way, recycling of mercury-containing lamps is the direct responsibility of management companies and homeowners associations.

Require them to place containers within walking distance of your home.

They must do this by law.

In many European countries the principle applies: “He who pollutes pays.”

Therefore, recycling and disposing of old batteries is a headache for manufacturers and importers.

They initially include the cost of collection and disposal in the price.
Our legislators also want to come to the same rules of the game in this market in the near future.

Of course, all of the above does not mean that from one AA battery, every living thing within a radius of 20m will immediately die.

But more than 7 billion people live on earth. Most of them use a variety of different power sources every day.

In Moscow alone, several tens of millions of such products end up in landfills every year. Toxins from them will accumulate in living organisms, increasing the risk of developing cancer and other serious diseases, not only in us, but also in our descendants.

What then should be done with batteries and other hazardous waste? Recycle!

Why produce something anew if you can use old things and save raw materials. This is quite reasonable.

Of course, you can’t actually create new batteries from old ones in a factory.

But at the end you can get ingots of zinc, lead, cadmium, copper, and iron. And only then these materials will be used for new production.

In Russia there is currently one widely known similar plant in Chelyabinsk.

But it can't handle measly hundreds or even thousands of batteries. He needs tons, tens, hundreds of tons. But they are not there.

Therefore, the plant is still on the verge of breaking even. Recycling technology is very expensive.

Battery cells are sorted and sent to a crusher.

Almost immediately, the first important element, iron, is extracted from them.

It is deposited on magnetic tape, after which it is collected and sold to iron and steel enterprises.

It is impossible to isolate the remaining parts mechanically. Chemistry comes to the rescue. The acid dissolves the mixture, and in the crystallizer the graphite, manganese and zinc are separated from each other.

They are packaged and sent to production.

Recycling 1 kg of batteries costs more than 100 rubles. At the same time, it is difficult to sell recyclable materials.

For example, recycled zinc costs 1.5 times more than virgin zinc. Which is why it is not in demand.

You can find out where the best place to return used batteries is on the website RecycleMap.ru. IKEA stores also accept old batteries.

By handing over batteries to collection points, many are confident that in this way they are personally saving air, soil and water, not only for themselves, but also for future generations.

Why you can throw batteries in the trash

Well, now, a few words about the opponents of such categorical measures regarding batteries outlined above.

Many are inclined to consider them mostly myths and misconceptions exaggerated by environmentalists, in order to obtain additional information. financing for their projects and production related to them.

Firstly, you need to clearly understand that current sources are:

• primary - disposable batteries

• secondary - batteries

The primary ones include saline and alkaline. Their charge is enough for one time, after which they are mercilessly thrown away.

Secondaries can be recharged hundreds of times. These are nickel-cadmium, lithium-ion, nickel-manganese batteries.

They are thrown away after a long period of use. The icon of a crossed out trash can is almost always printed on batteries.

But on simple batteries, you can often not find it. It is battery models that are rich in heavy metals that environmentalists scare us with - lead and cadmium.

By and large, disposable batteries do not use hazardous metals. All environmentalists scare us with the terrible cadmium and its consequences, but there is no cadmium there!

Moreover, a significant part of its compounds are almost insoluble, which means they will slowly turn into sedimentary rocks.

Since the 60s of the last century, mercury has generally stopped being placed inside these products. But the horror stories remain.

What is there? Coal, a little zinc, saline solution, alkali.

Although alkalis are harmful to our mucous membranes, they do not have any particular impact on the environment. Moreover, in the acidic environment of general waste.

By the way, alkaline batteries are the same as alkaline ones, do not be confused.

That’s why people massively throw these AA, AAA and similar finger and little finger batteries into the trash. Without worrying at all about killing innocent hedgehogs and trees in the forest as a result of his actions.

Read on Ru.Wikihow.com which batteries can be thrown away and which ones cannot.

And the pollution figure of 20 m2 from one battery is not entirely clear. It is reprinted from article to article, but where did it come from? “British scientists” calculated it?

Why not 15m2 or 25m2? How does soil composition and soil type affect this area? Just questions, but even environmentalists don’t have concrete answers to them, just propaganda.

For example, at a recycling plant in Finland, batteries are used to make soil fertilizer. They remove the iron cases and grind their insides.

A badly rusted body is removed, as it has a negative effect on the soil. With the same success, one could collect nails or rusty bolts, handing them over to all sorts of “eco-boxes” and saving nature.

By the way, for large retail chains these same eco-boxes are an additional means of attracting customers. A person who donates a battery will make more purchases in this store than in another.

This is the so-called “customer loyalty” effect.

That’s why they carry out all sorts of PR campaigns about this. However, as a rule, everything ends with PR.

In 90% of cases, your batteries and light bulbs, put into the store's "eco-bin" trash bin, end up in another trash bin, just a larger one.

And ultimately, in the same landfill where you could have taken them in the first place.

It is not for nothing that legislators paid attention to this and, since 2016, have banned retail chains and other organizations that do not have a special license from engaging in this imitation of environmental activities.

The batteries are classified as waste of the second hazard class.

And all schools, shops and retail outlets that have taken on the role of environmental activists and volunteers risk receiving a real fine for this.

Amounts reach 250 thousand rubles.

Therefore, some people, familiar with the entire chain of advertising campaigns and with where the battery actually ends up at the end of its journey, initially throw it in their trash can, bypassing unnecessary intermediaries, and without feeling any remorse about this.

What can be made from batteries, including used ones

Home appliances and toys use batteries of various types as batteries, which become unusable after a while. To avoid throwing them in the trash and harming the environment, you can make something interesting or useful out of batteries, and then hand them over to a special collection point. New and used items are suitable for science crafts.

What can be made from batteries

The simplest games with many batteries are to make letters, numbers and pictures out of them. The entertainment is suitable for children over three years old. An adult must participate in the game, who will ensure the integrity of the battery case and will not allow the child to lick or disassemble the batteries.

Batteries can be used as a construction set, making various shapes out of them

You can repeat a physics course with schoolchildren using old and new batteries. Crafts can be used not only for experiments. Knowledge and skills will be useful if you find yourself in extreme conditions.

Lighter

Materials for the product:

• a new or used battery, but still in working order;
• a piece of foil 8 cm long and 6–10 mm wide. You can use food or chewing gum foil;
• flammable material (newspaper scraps, cotton wool, hemp).

Manufacturing instructions:

1. The foil strip is cut so that its original width remains the same at the ends, and a 2 mm jumper remains in the center. Depending on the power of the battery, you may need a strip of foil with a larger or smaller width than stated. This can be established experimentally.
2. The location of the positive and negative terminals on the battery is determined.
3. The battery and foil are brought to the material that they plan to set on fire. First apply the foil to the negative terminal, then to the positive one.

   The structure is held with two fingers, the thin part of the foil heats up and ignites the prepared material

4. If you use chewing gum foil, it will ignite on its own without any other material.

   It is advisable to carry out this experiment with gloves so as not to burn your hands.

When conducting the experiment, you must follow safety precautions. Keep water and a trash can handy.

Do not use leaking or deformed batteries. Liquid leaking from batteries is toxic. In addition, damaged batteries may ignite or explode before the experiment is completed.

Motor or “helicopter”

For good contact with the battery, the ring is lowered a little lower

Materials for creating a kind of perpetual motion machine:

• new battery;
• thin wire;
• two paper clips;
• small magnet;
• sandpaper;
• reinforced tape.

Instructions:

1. The wire is wound around the battery, 5–7 turns are made.
2. Remove the resulting ring. The ends of the wire are bent around the ring and smoothed with sandpaper.
3. The paper clips are straightened and secured with tape, one on each side of the battery.
4. Bend the paper clips at an angle of 90˚ and attach the ring to them.
5. A magnet is placed on the battery and the ring rotates.

If the motor does not start immediately, the distance between the wire ring and the magnet may be too large.

In a similar way, you can make a “helicopter” or an engine in the form of a moving spiral.

The wire can be bent into a spiral, heart, rectangles, etc.

To do this, bend the wire into the desired shape, which is fixed to a round magnet. The battery is installed on top, that is, the structure is made vertical. The wire must simultaneously be in contact with the battery and the magnet. For a wire frame, it is important to correctly determine the center of gravity, then as a result of the experiment it will rotate.

Electromagnet

This magnet can be used to attract small metal objects

Materials for making an electromagnet:

• battery;
• copper wire - about one and a half meters;
• large nail or bolt.

Manufacturing instructions:

1. The wire is wound around the bolt, leaving free ends on opposite sides (they are needed for contact with the battery).
2. Attach the wire to the battery terminals. The magnet is ready!

What can be done from used batteries

A discharged power source can be charged for a short time if purchasing a new one is not possible at the moment. To do this, carefully deform the body, preventing it from being damaged. If the shell is cracked, then the battery can no longer be placed in the electronics, since caustic liquid will leak out of it and ruin the device.

From a battery that has served its intended purpose, you can make a lamp, designing it according to your own wishes.

Take a small light bulb for crafts so that the remaining battery power is enough to produce a glow

To make sure that the battery is discharged, it is thrown onto the table with the minus side down from a height of three centimeters. A new battery falls with a dull sound, a dead battery falls loudly and bounces off.

To make it you will need:

• used but not damaged battery;
• bulb;
• thin copper wire;
• scotch;
• paper and clay for creativity.

Manufacturing instructions:

1. The wire is divided into two parts.
2. Tape one part of the wire to the terminal with a negative charge.
3. The second part is wound around the metal area of ​​the lamp.
4. The free end of the wire (the one on the lamp) is attached to the second terminal of the battery.
5. In order for the lamp to light up, the circuit must be closed.

The light from the lamp is quite bright.

You can turn the product into an interesting craft by covering the battery with cardboard or plasticine. The resulting flashlight can become a lighting fixture in a dollhouse or become a bug with antennae terminals. Play with the product under adult supervision.

Similarly, you can highlight the glass.

Rules for recycling old batteries

Collection points for old batteries are being organized in cities, where exactly you can find out from the Internet

You should not throw away used power supplies with the rest of the trash; this pollutes the environment. Batteries consist of the following elements:

• steel shell:
• manganese oxide;
• electrolyte;
• zinc;
• graphite;
• paper and plastic.

The release of harmful substances begins after the metal casing rusts. Chemicals penetrate into the upper layers of the soil and, together with precipitation, enter groundwater. Together with them, dangerous compounds end up in the seas and rivers.

A safety threshold has been established for the content of chemical elements in water, air and soil. Exceeding the standards means that being on the territory is dangerous for human and animal health.

For these reasons, a battery recycling system has been developed. Product elements are used in various fields: metallurgy, production of pencils and fertilizers. After recycling, only 5% of the total weight of the battery must be recycled.

The only plant in Russia that recycles power supplies is located in Chelyabinsk. All collected batteries are delivered to this plant for recycling. The city has a developed metallurgical industry, so the resulting metal is used in local factories.

what can be made from a battery

It should be remembered that conducting experiments with batteries should not cause harm to others. Therefore, you should not trust this work to a child. The adult should also evaluate his level of training so that he is able to assemble the chains correctly.

Recycling batteries, what's valuable there

Have you ever wondered how many batteries citizens throw into trash containers every day? Thousands! Although each of them has a warning sign that it is prohibited to throw away used batteries.

But since we simply do not have a collection network for used batteries, they end up in landfills, causing enormous harm to the environment. Although their processing is a profitable business.

In particular, at the Lvov enterprise Argentum, which processes waste and secondary raw materials containing precious metals, they are trying to prove that throwing away batteries is wasteful.

12 tons daily in the trash instead of recycling

“It all started in 2011, when licensing for activities with batteries was canceled in Ukraine,” Taras Kogut, director of the innovation center of the Argentum State Enterprise, tells UM. – Although we have been interested in recycling batteries for a long time, since 2005. But after the liberalization of the law, they began to conduct experiments in laboratories and created appropriate conditions at the plant.

Then we turned to the public to ask people to collect batteries and bring them to us. The first to respond was a specialized store, which installed a box for collecting used batteries. From this store alone we received 50 kilograms monthly.

Now that residents are well aware of the possibility of recycling, 300 kilograms of batteries per month are collected in the box of this retail establishment.”

For more than a year, scientists from the enterprise and chemists from Lviv Polytechnic and Ivan Franko Leningrad National University studied the composition of batteries and various methods of processing them. There is a lot of useful information on battery recycling in open sources, but you won’t find the technological process itself on the Internet. Therefore, I had to do everything, as they say, with my own hands. Although there is still work to be done, because the initiators of recycling have not been able to figure out how to recycle lithium batteries.

“Over the course of a year, at the Polytechnic facility, we have tried almost all processing methods,” says Taras Romanovich. “During this time, we have learned to make many interesting things from batteries, but, unfortunately, most of them are not economically justified. For example, we know how to extract medical grade potassium permanganate from a used battery. We also learned how to make electrolyzed zinc solution and pure zinc. We also know how to clean various components found in batteries.”

The battery contains 15 percent zinc

It is more profitable to remake batteries to obtain zinc than to extract it from ore. The battery contains 15 percent zinc. For comparison, the ore contains only 0.15 percent zinc. And in general, according to the director of innovation, a battery is an ideal secondary material, because it contains at least five useful components. At the same time, in Ukraine, 12 tons of batteries are thrown into the trash every day.

How a battery turns to dust

The battery recycling area is located in one of the premises of the plant. Some of the collected material is stored on another train, and some awaits its turn in sorting.

At the site, the batteries are sorted: some are in boxes on the shelves, some are already sorted in plastic bottles, and another bunch is on the table. They will be sorted. In total there are about five tons of batteries here.

At first glance, for the average person, five tons is the size of a truck, but we should not forget that the material is quite heavy, so the volume is much smaller. So, first, all brought batteries are weighed.

Returning to the sorting table, it should be noted that sorting batteries is painstaking work, because you need to take them manually. Although, according to Taras Kogut, a few days are enough to sort through everything that is brought in a month.

The table has drawers for different types of batteries, and on the wall there is a “cheat sheet” that shows the main characteristics of different types of batteries and their possible images. So, all the material is sorted into batteries, lithium batteries, salt batteries and alkaline batteries. The majority, four-fifths, are alkaline or salt batteries.

The rest, non-standard batteries (batteries from phones, laptops), are examined in the laboratory. They are not yet processed because their quantity is not enough for industrial processing.

After sorting, the finished batch of used batteries goes into the shredder. This rather “cunning” machine was made at the factory by the hands of local craftsmen. It was not easy, only the third version of the shredder turned out to be effective. A young man stuffs a handful of batteries into the neck and the machine, noisily, grinds the batteries into “flakes” in just a few seconds.

From one hundred kilograms of used batteries we get 40 kilograms of finished raw materials

A worker in a mask, overalls and gloves carefully removes the crushed substance with a spatula and feeds it into a mechanical separator. The resulting powder can already be used for metal smelting. “In fact, it is carbon with inclusions of zinc and chlorine compounds,” explains Mr. Kogut. – This is already a pretty good raw material for metallurgy. To understand the scale: from one hundred kilograms of used batteries we get 40 kilograms of this raw material.”

One hundred kilograms of batteries yield from 15 to 30 kilograms of zinc and iron

The carbon is then passed through magnetic seeders. For this purpose, the areas are equipped with a vibrating table. It should be noted that all experimental equipment was made at the factory and at our own expense.

After sowing, the material enters a magnetic separator, which divides the mixture into iron and zinc. One hundred kilograms of batteries yield from 15 to 30 kilograms of zinc and iron.

Zinc with impurities of carbon and manganese can be used in metallurgy as a softener or liquefier of metal. And the resulting iron is sold for scrap.

Look into the battery

“The battery contains carbon, manganese, zinc, iron - the main elements,” says the expert. – We consider associated elements – paper, cardboard, plastic, resin – as inert waste. There is about three percent of it in the battery. Modern batteries contain almost no mercury elements. We find only a few of these batteries and for now we just put them aside for preservation.”

In the world of batteries, silver-based batteries occupy a special place. They are designed for watches, key fobs and various medical and military equipment. They are also used a lot, but they are not included in the Argentum State Enterprise. Recycling of such batteries has existed for a long time and in the shadows.

According to Taras Kogut’s calculations, if Ukraine began to recycle batteries on an industrial scale, then 10-15 recycling sites would be enough for the country. And this, in turn, would give jobs to at least two hundred people.

“The main thing in processing is not the technical process at factories, but to establish logistics at the legislative level,” explains Taras Kogut. – It is necessary to motivate the retailer and provide a system for collecting used batteries from stores. At the plant we developed our own scheme and implemented it.

We talked with associations of condominium associations, tried to convey information to battery suppliers. By the way, there are only five of them in Ukraine. At the same time, three of them own 80 percent of the entire Ukrainian market, and the remaining two – 20%.

However, suppliers do not want to take on extra hassle, because they understand that in Ukraine there is no legislative framework that would regulate the disposal of used batteries.”

But in developed countries, it is the supplier who is primarily interested in recycling batteries. Processing is even included in the price of the product. The most interesting thing is that when buying batteries abroad (after all, they are not produced in Ukraine), suppliers already pay for their disposal. But all the money remains with the manufacturer, and in our country the used material is simply thrown into the trash.

The environment is suffering

“We constantly monitor the contents of modern batteries,” says Taras Kogut. “And we can say for sure that there are no extremely toxic elements there.” Of what gets into the soil, only zinc is harmful. However, no one can predict the consequences.

The fact is that active elements can react with what is already in the landfill. The temperature in the landfill itself can reach more than 100 degrees (spontaneous combustion occurs). No one has yet studied what chemical reactions occur there.”

There are no extremely toxic elements in batteries; only zinc is harmful

Through the efforts of public organizations and concerned citizens, over the course of the year we managed to collect more than 10 tons of used batteries for recycling. “All this was collected by the hands of activists and caring people who, without any additional motivation, understand the need for a clean environment,” concludes Mr. Taras.

“This once again proves that people want to behave correctly and not pollute the environment. We just need to create the appropriate conditions for them. We see that people don’t spare their time and take used batteries to a special box.

Likewise, community activists spend their time packing and sending the material to the plant.”

According to Mr. Kogut, many problems with household waste can be solved in the same way. So, for example, you can store and recycle mercury lamps, which, according to experts, are much more harmful than batteries. Now they are simply thrown into a landfill, because it is impossible to collect material without a license. This is an example of how ill-conceived bans and over-regulation lead to poisoning of the environment and people.

“From the experience gained during the implementation of the project for organizing the collection and recycling of used batteries, we can conclude that the recipe for the success of such projects is high public activity, entrepreneurial initiative and responsibility of producers and consumers,” summarizes Taras Kohut.

How to make a battery from zinc, copper and acid

The well-known citric battery uses acid to dissolve zinc and release electrons, which are returned to the solution to form hydrogen gas. These batteries are quite weak compared to commercial ones, but they can be a useful learning tool. Or they can be used in a radio, and it will work just as well as with batteries from the store.

Why are these batteries weak? Part of this has to do with chemistry and metals, but I wanted to get the most out of this battery by decreasing the distance between the zinc and copper and increasing the surface area of ​​both. To do this, I created a stranded, coiled wire cord as a barrier between the metals, also using the spacer as a permeable substrate for the electrolyte, vinegar.

Three cells in the series produced 2.4V and illuminated a small LED, although the current was very low.
The production of hydrogen gas was very noticeable. I wanted to share these techniques with you in hopes that this construction technique will inspire other projects.

Inventors shop at a budget Chinese online store.

The battery needs zinc, copper and acid. Regarding zinc, I did some research and found that galvanized metal must be coated with zinc. Unfortunately, the wire packaging doesn't explicitly say it's zinc, but I think it is. Galvanized steel wire provides a source of zinc. Copper wire can be easily found at most craft and hardware stores.

I decided to use white distilled vinegar for the acid because there are no extra sugar or salt molecules to think about. To keep the two types of wires close but not touching each other, I suggest shoelaces. They will absorb the electrolyte but maintain a small distance between the metals.

For tools: I needed scissors, wire cutters, an electric drill, and a C-clamp.

Step 2: Create Stranded Wire

DIY electronics in a Chinese store. Take about 6 meters of wire and wrap it around the clamp. Insert the two loose ends into the chuck of your electric drill and tighten them. Spin the wires together to form a stranded wire. Repeat with both types of wires.

Twist the copper wire two more times to thicken it. This will become the base of our hollow cord.

Step 3: Winding the Wires onto the Cable

Cut off one end of the cord and insert the thicker copper stranded cable into the hollow cord. Push the copper cable all the way through, hopefully you will have a little extra at the end, otherwise you will need to keep a little open so you can make the electrical connection later. Start wrapping the galvanized rope around a cord with a copper core. Wrap it all up until you reach the end.

We now have a large amount of zinc and copper ready to react with very little space between them, but without touching each other. The string will absorb the acid.

To save space, wrap the cable around or around itself.

You can be as creative as you like here, just remember that the bare copper and one end of your galvanized wire are our voltage test jumper wires.

How to make a battery easily

A battery is a chemical source of electrical voltage. All commercially available batteries have similar operating principles. The positive terminal of the product is made of manganese or lithium, the negative terminal is made of zinc or aluminum. You can assemble the battery yourself from simple materials.

Batteries are a source of electrical voltage.

Homemade battery from improvised means

The battery can be made from materials whose properties are similar to those of substances used in industrial conditions.

From lemon

The acid contained in the juice of the fruit acts as an electrolyte. Electrodes are made from thin wire, nails or needles. The iron element is the anode, the copper element is the cathode. The lemon is cut in half and placed in a small container (jar or glass). The wires are connected to the electrodes, the stripped ends are inserted into the pulp of the fruit at a distance of 1 cm from each other.

Using a multimeter, measure the voltage supplied by a homemade galvanic cell. If it is not high enough, several lemon batteries are connected in series.

Jar with electrolyte

Using this method, it is possible to assemble a device that resembles the world's first battery. Electrodes are made of copper and aluminum. Elements must have a large area. The aluminum electrode is connected to the wire using a clamp or bolt, while the copper electrode is soldered. The parts are immersed in a jar at a short distance from each other. A lid with holes is used for fixation. The following compositions are used as electrolytes:

Making batteries with your own hands.

1. Ammonia. The substance is mixed with water in a ratio of 1:2. Ammonia cannot be used as an electrolyte. A suitable substance (ammonium chloride) has the form of a white, odorless powder. It is used as a fertilizer or soldering flux.
2. Sulfuric acid solution. The substance is mixed with water in a ratio of 1:5.

   You cannot pour the acid first. In this case, the added water boils and splashes fall on the person’s skin and clothing.

The solution is poured into a glass container so that the distance to the edges of the jar is at least 2 mm. Using a multimeter, measure the resistance and calculate the required number of batteries.

The principle of operation of a homemade element is similar to that of a salt power source.

Copper coins

The electrodes are made of aluminum and copper; 9% acetic acid is used as the electrolyte. Coins are cleaned of dirt by soaking them in vinegar. Circles are cut out of cardboard and foil. Cardboard products are soaked in a solution of acetic acid; they must absorb the electrolyte. A column is laid out from circles and coins.

The cardboard piece is placed first, the foil piece is placed second, and the coin is placed third. Wires are pre-connected to the extreme elements. Instead of soldering, the cables can be pressed to metal parts and sealed with tape. When the battery is used, the coin becomes unusable. You should not make power supplies from valuable products.

Battery in a beer can

The negative terminal is the body of the aluminum container, the positive terminal is the graphite rod. You will also need coal dust, polystyrene foam, water, paraffin candles and salt.

The top of the jar is removed, a circle is cut out of foam plastic, which is inserted into the container. A hole for the rod is made in advance. The latter is installed in the central part of the jar. The remaining space is filled with coal dust.

The material is impregnated with an aqueous solution of salt (3 tablespoons of product per 0.5 liters of water). The edges of the jar are filled with paraffin.

Potatoes, salt and toothpaste

The potato battery is intended for one-time use. It is used to produce a spark by shorting wires. To make the element you will need a large potato, insulated copper cables, salt, wooden sticks and toothpaste. The assembly is done like this:

1. Potatoes are cut into 2 equal parts. A recess is formed in one half, where salt and paste are added.
2. The ingredients are mixed until smooth. The electrolyte should fill the depression.
3. In the other half of the potato, make 2 holes at a distance of 1-2 cm. They should coincide with the filled recess.
4. The stripped ends of the wires are inserted into the holes, and the halves are combined. The wires must be immersed in the composition.
5. Potato parts are secured with toothpicks. After a few minutes, the cables short out, creating a spark to start the fire.

Step-by-step instructions for making a battery

Cylindrical batteries with a height of 50 mm can be easily made at home.

Required materials and tools

Before starting the experiment, prepare the following materials and tools:

• corrugated cardboard;
• flat copper washers with a diameter of 1 cm - 12 pcs.;
• flat zinc washers with a diameter of 1 cm - 15 pcs.;
• purified water;
• heat-shrink tubing;
• acetic acid 70%;
• salt;
• soldering iron;
• containers for preparing solutions;
• multimeter;
• sandpaper.

Corrugated cardboard is one of the materials for making batteries yourself.

Cleaning the washers

The homemade battery is based on 11 copper-zinc washers that produce a voltage of 0.15 V. The parts must participate in chemical reactions, so they are cleaned with sandpaper. The result is a smooth, shiny surface.

Electrolyte preparation

Metals create electric current, but it requires a medium to conduct it. The electrolyte is made from 120 ml of water, 4 tbsp. l. salt and 30 ml of acetic acid. The ingredients are mixed and infused for an hour.

Working with cardboard

To form the required distance between the washers, lay out circles cut from corrugated cardboard. After cutting, the material is impregnated with the solution prepared at the previous stage.

Tube stretching

Before placing the copper-zinc washers, the tube is given the desired diameter. Using needle nose pliers, the product is stretched by 10% of its original size.

Device testing

Electrolyte-impregnated cardboard is placed on the copper washer. The multimeter is switched to constant voltage mode. The black wire is connected to the copper part, the red wire to the zinc part. A value of 0.05-0.15 V should appear on the device screen. This is enough to create a battery from 11 conductive components.

Final battery assembly

The elements are laid in the following sequence: copper - zinc - piece of cardboard. Each part is aligned perpendicular to the axis of the tube. For convenience, the washers are pressed with a thin rod. Having installed the last part, the homemade battery is compared with the factory one. If necessary, an additional zinc washer is introduced. The tube is heated, creating something like a battery. Excess is removed.

Contact installation

Using a heated soldering iron, solder points are welded to the ends of the resulting structure. When installed in the socket, the soldered parts must touch the contacts of the battery holder.

How to galvanize a body using a battery

Buying a new car is a pleasure that not everyone can afford. That's why many car owners still drive old, beat-up cars. Even if you invest a lot of money, time and effort into restoring the technical part, the stumbling block may be the appearance of the vehicle.

Many car enthusiasts have encountered such an unpleasant phenomenon as corrosion. You can try cleaning cars that are fairly rotten with sandpaper, treating them with putty and primer, or applying acrylic. However, after a few months the problem will still return.

Why is this happening? Why don't a sandblaster or a sander solve the problem? The point is that you are cleaning off the rust on top, but not removing what is inside.

And corrosion is a disease. And if it makes itself felt at least once, it is almost impossible to get rid of it. There are several ways that allow you to forget about rust for several years. We will tell you about them today.

Treatment with salt batteries

It all starts with preparation. You will need:

• Salt batteries. For example, for a VAZ-2107, five salt batteries will be quite enough.
• Degreaser.
• Several types of sandpaper.
• Putty and a clean rag.
• Wires.
• Acid – phosphoric acid or soldering acid.
• Epoxy primer.
• Citric acid.
• Varnish, paint.

The area damaged by corrosion is thoroughly cleaned and galvanized with a battery. To do this, the top shell with the name is removed from the battery, and a wire is fixed to the body. The second end is connected to a car battery or car battery charger. The longer the wire, the better - it will be more convenient for you to work.

Then you need to apply voltage - the minus goes from the battery or charger to the body. We connect the light bulb in parallel so as not to damage the battery. After this, the battery is wrapped in a rag and soaked in acid. Slowly move this simple device around a protected area. You will hear a hissing sound and the iron will be covered with a light layer of zinc.

The process is long but effective. When the treatment is finished, you need to prepare a solution with citric acid and wipe the treated metal. Then degrease and dry, apply epoxy primer. Although it will cost 500-600 rubles per cylinder, it will hold up perfectly. Next, if necessary, putty is applied, primed and a base is applied. After this, the surface is covered with varnish or acrylic paint.

Other galvanizing methods

In addition to the processing method described above (galvanic), cold and thermal galvanizing is used. Let's look at them in more detail.

Cold galvanizing

Specialized stores sell finely dispersed zinc in cylinders. It is applied to the body like paint. It is far from the most reliable option, but it is the most affordable. It is used if you need to galvanize a budget car.

Thermal galvanization

It is almost impossible to implement it at home. At the factory it’s a different matter. The car body is dipped into molten zinc and rolled. Ford, Volvo, Porsche, etc. cars are subjected to this treatment.

Thus, cold and galvanic galvanizing can be done with your own hands at home, without the help of specialists. The event, although long, is low-cost. Absolutely every car enthusiast can hold it in his garage.

Do-it-yourself galvanizing of a car body with video and photos

The article will talk about galvanizing a car body with your own hands. At the end of the article you will find a video on the same topic. Galvanizing a car body is quite a scrupulous matter. Therefore, we recommend that you initially practice on any other iron surface, and when you have already become proficient, you can safely start galvanizing the body of your car with your own hands.

To galvanize iron, we need soldering acid (zinc chlorine), you can buy it at a radio parts store, or you can do it yourself - throw pieces of zinc into hydrochloric acid until the reaction stops; zinc electrode; a glass of salted AA battery; a piece of fabric or cotton wool; the wire.

We connect the wire to the battery positive. Disconnect the positive terminal. The minus remains on the body.

We clean the metal so that there is not a drop of rust left on it.

We saturate the fabric with soldering acid.

We begin to move our fabric tip along the metal surface.

This is the reaction that takes place.

We continue to drive along the surface.

Anyone who has the patience can process the entire car body in this way. Afterwards everything is washed off with water. And for those who want to play it safe, they can wash it off with a light alkaline solution, for example, a solution of baking soda. Zinc can be obtained from salt batteries or from old Soviet carburetors. You can use a charger instead of a battery. Here at this place 2 years ago we had severe rust, which we cleaned and galvanized using this method.
