Battery

Battery refers to a space in a cup, tank or other container or composite container containing an electrolyte solution and a metal electrode to generate electrical current, a device capable of converting chemical energy into electrical energy. It has a positive electrode and a negative electrode. As technology advances, batteries are broadly referred to as small devices that generate electrical energy. Such as solar cells. The performance parameters of the battery mainly include electromotive force, capacity, specific energy and resistance. By using the battery as an energy source, it is possible to obtain a current having a stable voltage, a stable current, a stable power supply for a long time, and little influence from the outside, and the battery has a simple structure, is convenient to carry, and is easy to operate in charge and discharge, and is free from external climate and temperature. The impact, stable and reliable performance, play a big role in all aspects of modern social life.
