Battery
Battery means a device capable of converting chemical energy into electrical energy in a portion of a cup, tank, or other container or compound container containing an electrolyte solution and a metal electrode for generating electric current. With positive, negative points. As technology advances, the battery refers to small devices that generate electricity. Such as solar cells. Battery performance parameters are electromotive force, capacity, specific energy and resistance. Using the battery as an energy source, a specific stable voltage, a stable current, a stable power supply for a long time, and a current that is less affected by the outside world can be obtained. The battery has a simple structure and a portable battery. The charging and discharging operation is simple and easy. The impact of stable and reliable performance in all aspects of modern life play a huge role.
