• PURPOSE Electric battery — a reusable cyclic chemical power source designed for energy storage and autonomous power supply of various electrotechnical devices and equipment, as well as for providing backup power sources in medicine, manufacturing, and other fields of human activity. • SCOPE OF APPLICATION In everyday life, batteries are found in mobile phones and under the hood of a car, but batteries are used much more widely. In electronics, they are power sources for uninterruptible power supplies; in security systems, the battery is used as an alternative to the stationary power grid. Batteries are also widely used in transport: railway cars, trolleybuses, hybrid cars, electric cars, trolleybuses, etc. • PRINCIPLE OF OPERATION The principle of operation of a battery is based on the reversibility of a chemical reaction. The battery's capacity can be restored by charging, i.e., by passing an electric current in the direction opposite to the current during discharge. Several batteries connected in a single electrical circuit constitute a battery pack. The principle of operation of lead-acid batteries is based on electrochemical reactions of lead and lead dioxide in a sulfuric acid medium. A lithium-ion battery consists of electrodes (cathode material on aluminum foil and anode material on copper foil) separated by porous separators soaked in electrolyte. The charge carrier in a lithium-ion battery is a positively charged lithium ion, which has the ability to penetrate the crystal lattice of other materials with the formation of a chemical bond. In a lithium-polymer battery, a polymer material with inclusions of a gel-like lithium-conducting filler is used as an electrolyte. Often used in mobile phones, digital equipment, etc. • ADDITIONAL ACCESSORIES OR ACCESSORIES
