In today's world you will not find a single person who does not use batteries. They work with flashlights, clocks, children's toys, remote controls and more.

There are several types of them, differing in shape and size: large, medium, finger, little finger batteries, square and round. They can be primary, used once, and secondary, used repeatedly, as they can be recharged.

Mini batteries are a source of electrical energy. It is formed as a result of a chemical reaction occurring inside, converting chemical energy into electrical energy. The shape of the batteries is not random. A tall and rather narrow cylinder is better at dissipating heat and has much less resistance inside the battery.

Any little finger batteries have the same device: inside there is an electrolyte and two different metals. One metal is an oxidizing agent - an anode, it accepts electrons.

The second metal is a reducing agent - a cathode that can donate electrons. Castelectrolyte can be solutions of alkalis, s alts or acids. As a result of the interaction of these substances, a chemical reaction occurs, causing an electromotive force, which contributes to the transition of one energy into another.

Mini batteries can withstand a small load of 1.2 - 1.6 V. But this is enough for some devices, such as a remote control or a small player.

There are several most widely used types of batteries, different in their chemical composition:

  1. S alt - mainly used for wall clocks and various remotes.
  2. Alkaline or alkaline - used for devices that need high current: a flashlight, an electric razor, a radio-controlled car, a camera and others.
  3. Lithium - are rarely used today. Available in limited quantities for a specialized type of battery and for a special type of equipment, equipped with a number of safety devices and special controllers that monitor the charge level.
  4. Mercury - characterized by constant voltage and very high energy intensity, but are practically not produced due to the harmful effects of mercury contained in them.
  5. Silver - have a high energy intensity and work excellently in conditions of both low and high temperatures. Not mass-produced due to high cost.

Mizinchikovye batteries - one of the most common, convenient and widely used varieties in everyday lifebatteries. They are convenient to operate and store. For the most part, they are absolutely safe for human he alth.

Little batteries are the type of "energy storage" that can be used in absolutely any devices and devices. However, they do not require a large physical space for themselves, which makes them indispensable in compact devices.
