Lithium energy storage system is a system that utilizes lithium-ion battery technology to store and release electrical energy. It plays a crucial role in the field of modern energy and is widely used in areas such as power systems, electric vehicles, and consumer electronics. The advantages of lithium energy storage systems include high energy density, long cycle life, fast charging and discharging capability, and lower self discharge rate. These advantages make it an ideal choice to replace traditional fossil fuels, driving the global energy transition and the popularization of renewable energy.

The core of a lithium energy storage system is the lithium-ion battery, which works by moving lithium ions between the positive and negative electrodes to achieve the charging and discharging process. During the charging process, lithium ions migrate from the positive electrode to the negative electrode through the electrolyte; During the discharge process, lithium ions migrate from the negative electrode to the positive electrode. In addition to the battery itself, lithium energy storage systems also include battery management systems (BMS), thermal management systems, inverters, and other auxiliary equipment. These components collectively ensure the safe operation, energy optimization, and service life of the system.
