At present, most electric vehicles are equipped with lead-acid batteries, because lead-acid batteries have low cost and high cost performance. Prandtl of France invented the battery with lead as electrode. This kind of battery is unique in that it can be used repeatedly, so it is called "lead-acid battery".

Noun explanation:

Battery refers to a part of the space of a cup, can or other container or composite container containing electrolyte solution and metal electrodes that generate current, and a device that can convert chemical energy into electrical energy. Divided into positive electrode and negative electrode. With the development of science and technology, batteries generally refer to small devices that can generate electricity. Such as solar cells. The performance parameters of the battery mainly include electromotive force, capacity, specific energy and resistance.

Using the battery as energy source, we can get a current with stable voltage, stable current, stable power supply for a long time and little external influence. Moreover, the battery has simple structure, convenient carrying, simple charging and discharging operation, stable and reliable performance, and plays a huge role in all aspects of modern social life.
