[0002] A battery refers to a cup, trough or other container or part of a composite container that contains electrolyte solution and metal electrodes to generate current. It is a device that can convert chemical energy into electrical energy. It has positive and negative electrodes. With the advancement of science and technology, batteries generally refer to small devices that can generate electrical energy. Such as solar cells. The performance parameters of batteries mainly include electromotive force, capacity, specific energy and resistance. Using batteries as energy sources, we can obtain current with stable voltage, stable current, long-term stable power supply, and little external influence. In addition, the battery has a simple structure, is easy to carry, and is easy to charge and discharge.
