Energy storage

Energy storage

With the gradual increase in the proportion of clean energy, energy storage plays a vital role in the generation side, grid side and user side of the power system. Due to the advantages of high energy density, flexible application and fast response, the permeability of electrochemical energy storage increases rapidly. According to CNESA data, as of the end of 2021, the world has been put into operation power storage projects cumulative installed scale of 209 GW, the cumulative installed scale of new energy storage is 25.4GW, sodium ion batteries dominate, market share of more than 90% to 23.1GW. The cumulative installed capacity of power storage projects in China is 46.1GW, accounting for 22% of the total global market size. As the core component of electrochemical energy storage, battery has a great risk of thermal runaway. From the perspective of safety, the thermal management of energy storage is very important.
