Battery

A battery is a device that contains electrolyte solutions and metal electrodes in part of the space of a cup, tank, or other vessel or composite vessel that generates an electric current, and can convert chemical energy into electrical energy. It has positive and negative poles. As technology advances, batteries generally refer to small devices that generate electricity. Like solar cells. The performance parameters of the battery mainly include electromotive force, capacity, specific energy and resistance. Use battery as a power source, can get a stable voltage, stable current, stable power supply for a long time, influenced by the outside world is very small current, and the cells of simple structure, easy to carry, easy to charge and discharge operation, not affected by weather and temperature, stable and reliable performance, in all aspects of life in modern society play a large role.
