Battery refers to a device that can convert chemical energy into electrical energy in a cup, tank, or part of a space in a container or composite container that contains an electrolyte solution and metal electrodes to generate electricity. With positive and negative points. With the advancement of technology, batteries generally refer to small devices that can generate electrical energy. Such as solar cells. The performance parameters of the battery mainly include electromotive force, capacity, specific energy and resistance. Using the battery as an energy source, you can get a specific stable voltage, stable current, long-term stable power supply, current that is little affected by the outside world, and the battery has a simple structure, easy to carry, easy to charge and discharge operation, and is not affected by the outside climate and temperature The impact, stable and reliable performance, play a huge role in all aspects of modern life.
