At present, power batteries and energy storage batteries are the most promising areas for the future development of lithium batteries. Batteries used for electric vehicles and energy storage devices are essentially energy storage batteries. At present, there is no difference in technical principles between energy storage batteries and power batteries, but due to different application scenarios, practical applications have different requirements for their performance, service life, etc.
Power and energy storage battery system products can be divided into battery cells, modules, and battery packs according to different product forms. The battery cell is the core basic component unit of power battery products. A certain number of battery cells can form modules and be further assembled into a complete set of battery packs. The final form of application in new energy vehicles is the battery pack.
