The structure of a finger, round, crown, and telephone battery

We often want to know what's inside a battery? What are its components? How does a battery work? So many people start disassembling it. But upon opening the battery, they discover some strange components. The information presented here is understandable even for children. This article will clarify the matter and attempt to answer your questions.

What's inside the battery?

Below, we'll examine the structure of four types of power sources. While the operating principle is essentially the same, these energy storage devices are composed of different components.

Composition of a finger battery

The battery consists of the following elements:

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

This is roughly what the composition looks like AA batteriesBut sometimes their design is different. For example, a structure might use only a carbon rod, a special dark powder, and metal elements.

The structure of a round battery

A flattened battery has a unique shape. Here's a cross-section of the battery:

1. Positive end
2. Negative pole
3. A porous pad soaked in electrolyte
4. Mercury oxide
5. Zinc powder

The battery design may be slightly different:

Energy Element Details:

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

Phone battery structure

The principle of a mobile phone battery:

1. Positive and negative pole
2. Anode glass
3. Cathodic contact
4. Separator
5. Compaction
6. Safety valve
7. Insulator
8. Cap
9. Partition
10. The body is aluminum or other

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

What does a Krona battery consist of?

This power source is designed as follows. The positive and negative contacts are located opposite each other at the top of the battery. A plastic base is located underneath them. A plate extends from the negative contact to the negative terminal, where it is firmly attached. The battery's composition is similar to the power sources described above.

Inside the metal rectangular cup are six rounded, flattened rectangles. Each is a separate battery. The dimensions of these elements are: Length: 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 in the middle. This battery design is cost-effective!

What's inside a 9V battery?

Here's a cross-section of the battery itself. Sometimes it can look like this.

 

But usually you can notice that crownmade according to the type shown 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 together.
5. Electrolyte.
6. Carbon rod
7. Inner film.
8. Insulation plates.
9. The battery device also includes a wrapper.

Battery case and what is it made of?

The battery case plays a very important role. It essentially holds all of its contents and prevents the components from falling apart.

Which batteries have a zinc casing?

Many people are interested in this question, and for good reason. Zinc can be used for various experiments. Or it can simply be sold. Zinc housings are salinePower supplies. They are usually labeled as being saline.

Recently, we've seen batteries with surfaces made of iron or tin. This is due to the contents of the power source itself. This type of casing is required for increased durability and protection.

What does the AA battery body consist of?

It has a simple design and consists of several parts:

• Upper
• Lower
• Lateral oval
• Marking

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

It looks like this:

You can make your own battery case. But it takes time. The video below shows how to make one using household items.

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 rarely used now.
5. Lithium
6. Zinc
7. Manganese
8. Aluminum
9. Iron

So, the composition of a power cell looks something like this! But the design of an energy cell cannot contain all of these substances at once.

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

Battery factory

There are 5 best manufacturers of power supplies in Russia.

Space

Kosmos has been manufacturing power sources in Russia since 1993. It has 35 factories both domestically and internationally, including factories in China. Power sources from this company are sold under the names "Kosmos Premium" and "Kosmos." This brand is widely known and has dealers in various countries. The company sells up to one hundred million of its power sources annually.

This battery factory has long established a positive reputation in the market. The company has received numerous awards for its work.

Photon

This company has been involved in energy sources since 2011 and has already become a leader. The company's success is due to its high-quality products. This company's battery design boasts excellent characteristics.

Batteries from this company have been tested and it turned out that they work long enough and are cheaper than, for example, the same Duracell. Company photonis engaged in the production of salt power supplies.

Liotech

This battery factory was opened jointly with the Chinese. It produces lithium-ion battery cells. The factory is located near Novosibirsk. The production area is enormous, occupying 4 hectares.

Thus, this plant proves to everyone that large-scale competitive production can operate in Russia. galvanic cellsIn 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, which gives reason to believe it is a truly reliable manufacturer. In 2011, specialized workshops for the production of lithium-ion polymer batteries were launched. This is where most of the production takes place. AA batteriesand batteries.

CCK

This company has been operating since 1993 and produces 4th and 5th generation lead-acid batteries. The plant also works to increase the capacity of its batteries and develops new materials. All of this company's products have a long service life.

The battery produced by this factory has a high number of discharge-charge cycles. This means it will last a long time and won't need to be replaced every 2-3 months.

How are batteries made?

Battery production begins with cutting steel strips into oval shapes. Next, they are rolled into a metal tube, which is then called the case. Chemical components such as graphite, silver catalyst, manganese dioxide, barium sulfate, zinc, thickener, and potassium hydroxide are placed inside. The battery's design isn't always simple.

Next, a press rolls the cathode chemicals into granules. A groove is then made on the housing to facilitate sealing. Then, a sealant is applied to the negative pole. Meanwhile, another machine cuts perforated paper. Glue is applied near the negative pole. While the housing moves along the conveyor, the glue dries.

Then, potassium hydroxide or electrolyte is injected. Zinc helium is then injected into the anode cavity. The zinc imparts a silvery-white color to the helium. A welding machine welds 4-centimeter nails to the battery cover. The charge will accumulate there before being discharged. The negative terminal is then closed. All edges are then folded back, and the cell becomes a self-contained cell.

A special electronic machine checks each battery for defects and for a charge of 1.5 volts. Then, all that's left is to apply the sticker. Once this is done, each battery is placed in an oven. The temperature in this device is 198 degrees Celsius, and the batteries are held there for only three seconds. This is necessary to ensure the sticker adheres properly.

Equipment for battery production

Various automated machines are used to create batteries. LIK and many other companies manufacture specialized machines. Battery design is often improved and modified.

Essentially, an automated production line consisting of several machines is being built. After all, a hollow cylinder must be created, a pressing performed, adhesive applied, the necessary chemical elements added, a sticker created and applied, and then the battery subjected to heat.

Here is an approximate lineup:

• Vibrating machine
• Machine for creating a body, machine for an inverted body
• Automatic flow separation machine
• Paper handling machine
• Assembling machine
• Wringing machine
• Ribbon
• Gateway
• Plate

Each company produces lines in its own way and therefore the composition may differ significantly.
