Lithium -ion batteries have the advantages of high energy density, long circulation life, small self -discharge rate, no memory effect, green environmental protection, etc., and have broad application prospects in the field of energy storage. At present, the technology of lithium -ion battery is important in cobaltate, lithium manganate, lithium iron phosphate, and lithium titanium titanate. From the perspective of market application prospects and technology mature, it is recommended to be the first choice for lithium iron phosphate cells as the field of energy storage.

The development and application of lithium -ion battery technology can be described as hot, and market demand continues to increase. As one of its important applications, the battery Residential Energy Storage System came into being, including small home energy storage, large industrial and commercial energy storage, and super super Large -scale energy storage power stations. Large Residential Energy Storage System is an important part of future new energy systems and smart grids, and energy storage batteries are the key to large Residential Energy Storage System.

Electric energy storage systems are equivalent to batteries. There are many applications for energy storage, such as power stations, communication base stations and data rooms for backup power supply. The spare power supply technology and power battery technology of the communication base station and the data machine room belong to DC technology, which is lower than the power battery technology. The content of energy storage technology is more extensive. In addition to DC technology, it also includes variables technology, grid access technology, and grid scheduling control technology.

At present, the energy storage industry does not have a clear meaning in what is electrical energy storage, but the Residential Energy Storage System should have two characteristics:

1. Residential Energy Storage System can participate in the power grid scheduling (or the energy in Residential Energy Storage System can be fed back to the main grid).

2. Compared with power lithium batteries, the performance of lithium ion batteries is low.
