Homemade battery from improvised means

A battery or galvanic cell is a chemical source of electric current. All batteries sold in stores, in fact, have the same design. They use two electrodes different composition. The main element for the negative terminal (anode) of saline and alkaline batteries is zinc, and for their positive (cathode) manganese. The cathode of lithium batteries is made of lithium, and a wide variety of materials are used for the anode.

An electrolyte is located between the electrodes of the batteries. Its composition is different: for salt batteries with the lowest resource, ammonium chloride is used. Alkaline batteries use potassium hydroxide, while lithium batteries use an organic electrolyte.

When the electrolyte interacts with the anode, an excess of electrons is formed near it, which creates a potential difference between the electrodes. When closing electrical circuit number of electrons due to...

The disadvantage of the "lemon" battery is that it gives a small current. In order to build a more powerful device, you need a few lemons and a few pieces of wire. But you can rummage through the shed and find other things from which you can also make a power source. Try to make a simple galvanic cell like Leclanchet. Pairs of electrodes in this case can be pairs of zinc-copper, aluminum-copper plates. The larger their area, the better. Solder the wires to the electrodes. If you have an aluminum plate, the wire will have to be wound or riveted to it. You will also need the most ordinary glass glasses. Immerse a pair of electrodes in a glass so that they do not touch each other. You can put a plastic or wooden spacer between them. Prepare a solution for 100 g of water - 50 g of ammonia (ammonium chloride), or a 20% solution of sulfuric acid. Acid must be poured into water, and not vice versa. Carefully pour the solution into the vessel with electrodes so that up to the edge of the vessel and up to ...

It turns out that the batteries that we buy in the store are quite simple to do with our own hands at home.
To do this, we need copper coins, vinegar, salt, cardboard, foil and two wires with tips.

And the way we make our battery.

1. First you need to clear the coins. We put copper coins in a jar and fill it with vinegar. Add salt to it as well. After 30 minutes, the coins will be cleaned and become like new.

2. We take a sheet of cardboard and circle the coin 8-10 times.

3. Cut out cardboard coins.

4. Put them in a jar and pour vinegar again, leave for a while.

5. Take a sheet of foil. We fold several times until the folded foil takes the shape of a square, which is slightly over size coin.

6. On the resulting “square” of foil, we circle the coin.

7. And this time we cut out the “coins” from the foil.

8. We begin to collect our battery. First we put a copper coin, on top a circle of cardboard, then a circle of ...

Nowadays, we cannot imagine life without an electric battery, they are everywhere. The power of modern batteries is growing and the size is getting smaller and smaller. The basic principle of batteries is a chemical reaction! Their types are different, they are both alkaline and dry, and many others!

So how do you make a battery? We need two different metals, as the first we will take coins, for good contact I advise you to clean them up to flat surface, take the same foil (foil from a pack of cigarettes will not work), you can use a simple kitchen one.

In order for the current to begin to flow, acid and salt are needed, at home we have 70% acetic acid, but it will need to be salted (do not spare the salt). And finally, we need a sheet of blotting paper, you can take a thick fabric, but not with every fabric, so be careful when choosing!

Let's cut out circles from foil and paper, do everything neatly and evenly, the first layer is a coin, after we moisten the paper rounds in our vinegar-salt solution and put it on a coin after ...

Homemade battery

Hello my curious reader! Our old friend is with us again, who knows a lot of stories about electric homemade products. Here is his new story.

Do you understand that batteries can not only be bought at a kiosk? You know, I did not forget the lessons of physics and tried to invent a battery from what is lying around at hand.

And under our hands we found: 4 copper wire in isolation, 3 china goblets, table salt NaCl, and plain tap water. We also need foil, electrical tape.

Take a copper wire, all 4 pieces, and sharpen their ends one at a time. Then we wrap the foil around all the ends of the wires. Now, to each glass with electrical tape or adhesive tape, you can use adhesive tape, stick it along the wire and lower their edges there. It turns out one jumper connects two glasses, and the wires stick out a little longer from the extreme ones. In short, it turned out to be a chain, and like two ends stick out in a battery.

Now let's pour salt water into glasses and connect to ...

An article on how to make a simple DC battery from a glass of salted water.

How to make a simple battery with your own hands? It turns out to be very simple, all you need is aluminum and zinc strips, shielded wire, simple metal clamps, as well as a sealed plastic container, salt and plain water. The use of all these items should be quite sufficient to create a battery capable of generating electricity. The current capacity of this battery is enough to operate such simple devices such as LCD clock.

So, we take a plastic container, even an ordinary one will do for this. a plastic cup. On opposite sides of the cup we attach metal strips. Zinc on one side and aluminum on the other. Fill the glass with water in such a way that the strips are almost completely ...

Some more theory:
The battery case, which is made of zinc, can be covered with cardboard or plastic on the outside. Inside the case are chemicals in the form of a paste, and some batteries have a carbon rod in the middle. If the power of the battery drops, it means that the chemicals have been used up and the battery is no longer able to produce electricity.

2 step

Actually, the electricity in the battery is produced by combining aluminum, salt and copper.

3 step

So let's get started!
To make a battery, you first need to clean the coins with a cleaning agent. Next, circle 6 circles on the foil and napkin and cut them out. Carefully strip the ends of the wires with wire cutters or a knife. Twist the veins. Attach one wire to the coin with electrical tape (scotch tape), and the other to the foil mug. Immerse the paper circle in the warm saline solution. Then put the wire with a circle of foil in a saucer. Put a wet paper circle on it, put a coin on top. Overlay...

One way to cut costs utilities is the use of solar panels. Such a battery can be made and installed with your own hands.

What is a solar panel and what is it used for?

A solar battery is a device whose principle of operation is based on the ability of photovoltaic cells to convert solar energy into electricity. These converters are interconnected in common system. received electricity accumulates in special devices - batteries.

The larger the area of ​​the panels, the more electrical energy available

The power of the solar battery depends on the size of the field of photocells. But this does not mean that only large areas capable of generating the required amount of electricity. For example, well-known calculators can use portable solar panels that are built into their case.

More and more people are striving to purchase houses located far from the centers of civilization. There are many reasons for this, the main of which is probably environmental. It's no secret that the intensive development of industry has a detrimental effect on the state of the environment. But when buying such a house, you may encounter a lack of electricity, without which life in the twenty-first century can hardly be imagined.

The problem of providing energy to a building located far from the centers of civilization can be solved by installing a wind generator. However, this method is far from ideal. In order for the electricity to be enough for the whole house, it will be necessary to install a large windmill or several, but even in this case, the energy supply will be episodic, absent in calm weather.

To ensure the stability of the energy supply at home, effective solution is the joint use of a wind generator and a solar battery, but, to ...

You will need

• - Lemon
• - glass or glass
• - Copper and iron pins
• - 2 pieces of mounting wire in insulation
• - 2 wooden sticks
• - 2 push pins
• - Drill
• - soldering iron
• - Knife

Instruction

Stick copper and iron pins into the pulp at a distance of 0.5 - 1 cm. They will serve as electrodes in the battery. The negative electrode is iron, the positive electrode is copper. This must be taken into account when you connect, for example, to or a camera.

Solder the pieces of wire to the pins. If the device you are making battery, has an external input for a power source, you can connect the received battery to the device using this connector, having previously selected right amount elements. The elements must be connected in series using wires and soldering.

If the device does not have an external connector, take 2 wooden sticks and cut them to the shape and size of the batteries you normally use. Drill through them lengthwise so that you can thread the wires coming from the battery. The contacts are easiest to make from metal pushpins, to which the reins are soldered, after which the buttons are fixed on the ends of the sticks.

Insert the sticks into the battery compartment, observing the polarity. Contacts press to contact group. In this case, the container must remain open during operation of the device.

The disadvantage of the "lemon" battery is that it gives a small current. In order to build a more powerful device, you need a few lemons and a few pieces of wire. But you can dig into and find other things from which you can also make a power source. Try to make a simple galvanic cell like Leclanchet. Pairs of electrodes in this case can be pairs of zinc-copper, aluminum-copper plates. The larger their area, the better. Solder the wires to the electrodes. If you have a plate, the wire will have to be wound or riveted to it. You will also need the most common ones. Immerse a pair of electrodes in a glass so that they do not touch each other. You can put between them or a wooden spacer. Prepare a solution for 100 g of water - 50 g of ammonia (ammonium chloride), or a 20% solution of sulfuric acid. Acid must be poured into water, and not vice versa. Carefully pour the solution into the vessel with the electrodes so that there is at least 2 cm of dry space up to the rim of the vessel and up to the top of the electrodes. One such element gives an initial voltage of 1.3-1.4V. By connecting the elements into a battery, you can get a powerful source of current, sufficient to power mobile device. In this case, it is best to supply power through an external connector (through which a mobile phone is usually charged). Pay close attention to the polarity of the switch.

The first lead-acid battery was invented and tested by French physicist Gaston Plante. He twisted two lead plates into a roll, after laying a separating cloth between them. The roll was placed in a vessel and filled with salt water. As a result, if you apply voltage to the plates, then it is charged. And then, if you connect a light bulb to it, or something else, then for some time it could give the stored energy to the burning of this light bulb. Also, after charging, the energy in such a battery could be stored without loss for a long time. This marked the beginning of an era lead acid batteries.

But the most main disadvantage such a roll battery, it is a small capacity. Later it was found that if such a battery is charged and discharged several times changing the polarity (+ -), then the capacity increases. This is due to the fact that a layer of lead oxide formed on the plates, and the plates softened, becoming like a sponge. The acid could now penetrate deeper into the plates, allowing more lead to enter the chemical process.

These charge-discharge cycles, changing plus to minus and back, were called plate forming. To build up a thick layer of lead oxide, a lot of energy and time had to be expended. But later, one young man who worked as an assistant to Plante decided to do things differently. He decided to immediately apply lead oxide to the plates, thus he immediately got a more capacious battery. Subsequently, this technology has been slightly improved. They began to make lead gratings, which were smeared with lead oxide in the form of a paste. A paste was prepared from lead oxide, to which a little water or electrolyte was added and stirred until a thick consistency.

>

After more than 100 years, the technology for manufacturing batteries has not changed in principle. In production, lead gratings are also made by casting or stamping, and smeared with a paste consisting of lead oxide, plus additional additives that prevent the paste from disintegrating and give other desired properties. Also, the spacers between the plates are made of modern materials, which prevents the spread from falling out of the gratings and prevents the plates from closing to each other. In every factory, and for various types batteries (traction, starter, etc.) have their own subtleties, but in general the technology is the same.

>

Now you can think about whether you can do lead acid battery at home, so that it is profitable and effective. First of all, it's about lead, where can I get it? In unusable batteries, but if one car battery is melted down, then the output will be only about 1.5 kg of lead, and it will become clear that it is not profitable to extract lead in this way. In order to melt all the lead contained in the battery, part of which is in the form of oxide, sulfate and other elements that are contained in the grating, then a melting furnace and additional chemistry and conditions are needed, so at home on a fire it will turn out tin lead and a whole heap of slag.

Then you can buy lead, there is sheet lead, and in ingots, it is not expensive. If you make it from sheet lead, then you can roughly estimate the cost of one battery. If you delve into the literature, you can find out that from one square meter of plate area you can get a capacity of about 5-10Ah. Then for one can with a capacity of 50-100Ah, 10 sq.m of lead is needed. Since 6 cans are needed for 12 volts, about 60 square meters of lead are needed, respectively. The thinnest sheets on sale are 0.5 mm, the weight of one square meter of such a lead sheet is 5.7 kg. Since the sheet area works on both sides, it means that we need not 60 sq.m, but 30 sq.m for the battery. Then it turns out that a battery with a capacity of 50-100Ah needs 30 * 5.7 = 171kg of lead, the cost for 1kg is about 150 rubles, and the price for lead alone will be about 25,000 rubles, which is 5-6 times more expensive than a factory battery with a capacity of 100Ah.

>

It is possible to increase the capacity of the plates by molding, by means of charging and discharging, swapping plus and minus, but it is not known how many cycles need to be done to significantly increase the capacity. Plante molded the plates with electricity for three months. During this time, a lot of energy will be spent on molding, and as a result, the battery will only rise in price. From all this it is clear that it is not economically profitable to make a battery from sheet lead.

Yes, by the way, at the expense of the durability of the battery with sheet lead plates. Such a battery will last much longer, since the plates are solid and from deep discharges, high discharge currents, the spread will not leave, which simply does not exist, but the sulfation of the plates will be exactly the same as that of a conventional battery, therefore, in fact, this one is longer than usual. the battery will not last. True, it can be disassembled and cleaned from white plaque(sulfate) and he can continue to work.

The problem is that sheet lead does not have an oxide layer, or rather, it does, because of it the lead becomes dark gray color but this layer is too thin. Oxide is lead oxidized by oxygen, it is obtained in different ways in production. But at home, this dust is difficult to obtain. Of course, you can try to moisten the plates with water so that they oxidize on fresh air, but what oxide layer can be built up in this way and how long it will take is not known, so you can forget about a rolled battery made of lead sheet.

A good battery will turn out if you use lead foil instead of plates. So you can increase the area several times with the same weight, but you can’t make foil at home, and there is no pure lead foil on sale, and it would cost several times more than sheet lead of the same weight. That's why a good option with foil disappears. Or set up a rolling machine at home and make foil yourself.

You can try to make plates as they do at the factory, it is not difficult to cast gratings. They are thick and the casting mold is easy to make. But the problem is in the spread, because it consists of lead oxide, but how to make it at home. For example, something to erase lead into dust, or small chips, then pour it with water or electrolyte and constantly mix it in some kind of container so that it oxidizes on oxygen, but this is difficult and pointless to do at home, since the finished battery will come out much cheaper.

That's probably all I wanted to say in a nutshell. For myself, I concluded that DIY lead battery possible, but time-consuming and not profitable, so in this case, you can safely put a big and bold point. Also, reading a lot of information about other types of batteries, I came to the conclusion that nothing normal at home and using available and cheap materials will not work. If you have questions or any conclusions, please leave comments.

Do-it-yourself eternal battery 2.13 volts.

Today I will tell you how to make a battery that can last about half a year.

Today I’ll tell you how to make a battery that can last about half a year, or you can use an alternative, for example, a 12-volt solar battery manufactured by Chinaland Solar Energy.

We'll need:

• body, it will glass jar, plastic will not work;


• some piece of silver, in this case it is a spoon, it will serve as a core and will also participate in a chemical reaction;


• copper wire, it may be an old winding from some old electrical appliances;


• cling film, it will serve as insulation between the layers of the winding.

For the solution in which all this will happen:

• apple cider vinegar 6%, a teaspoon;


• glycerin, it is sold in any pharmacy, it costs ten rubles, four vials;


• ordinary table salt fine, a teaspoon.

First, wrap the spoon with cling film so that there is no direct contact with copper wire. I wrapped the spoon with a film, as you can see, the upper and lower ends of the spoon are bare, this is in order to interact with the solution, now let's start wrapping it with a wire. We leave a piece more authentic, this will be one of the contacts and wind the first layer. I wound one layer, as you can see the turns are not close to each other, there should be space between them for insulation. Now you need to wind the cling film again, I wound the second layer, the film needs to be wound as freely as possible so as not to impede the flow of the solution between the wires, and now you need to wind the second layer of wire and so on, the film, then the wire, and so on until you get bored.

The use of alternative energy sources is becoming more and more popular in our society. The accumulation of sunlight is useful not only for the environment, but also for saving money spent on electricity. If you care about environment or you just want not to spend extra money, then we offer you an article on how to make a solar battery with your own hands from improvised materials. Usually on the forums they write about photocells, the prices of which are very high. Thanks to our tips, you will learn how to completely build a homemade battery, which will greatly minimize your costs.

Materials for manufacturing

In order to make the device at home, you will need:

1. Copper sheet. Its average cost is about one hundred and fifty rubles per 0.9 m2. It will take about 0.45 m2.
2. Clamps in two pieces. Commonly referred to as "crocodiles".
3. Tester or microammeter. This device is needed to measure the current strength in the range between ten and fifty microamperes.
4. An electric stove with a power of 1100 watts to make the spiral blush.
5. A plastic bottle that you have to cut off the neck yourself.
6. Kitchen salt. Several tablespoons.
7. Heated water.
8. "Sandpaper".

Step-by-step instruction

So, to make a solar battery with your own hands, you must follow these steps:

• We cut off a piece of copper from a sheet of such a size that we can place it on a spiral electric tiles. For good result clean the cut piece from dust and dirt.

• Next, place it on the spiral plate. In connection with chemical reactions, when heated, copper will begin to change. That's when the copper turns black, count another 30 minutes so that the black layer becomes thick.

• Then turn off the appliance. Let the piece intended for making a solar battery with your own hands cool down. Cooling, copper and copper oxide will become different speed shrink. Then the oxide exfoliation will begin.

By the way, such a solar battery can produce several milliamps even without the sun! We recommend that you immediately look at the more serious option for using alternative energy sources, which we described in an article about!

A tutorial video on how to make a charger at home

Charging your phone from the sun

Now we will tell you how to assemble a solar battery that can charge mobile phone. By making a battery consisting of separate parts based on single-crystal silicon, problems with their soldering are not ruled out. If you are not sure that you can do everything yourself, it is better to choose already made modules. Well, if they consist of ten single-crystal elements, fit the size of your mobile phone case and have a voltage of five volts.

Solar cells may also be present in solar-powered calculators. In these devices for counting numbers, mainly amorphous elements are used, where a semiconductor layer is located on a small plate of glass. Considering that modules of this type give about one and a half volts, we need four pieces with a serial connection. Do not forget to solder a diode to the positive terminal of the battery, which will be used as a valve, preventing the battery from wasting charge through the solar panel. You can get the diode from the flashlight board. In order for our invention to serve more reliably, we fill the transverse edges of the modules with hot glue.
