energy storage is very important in power consumption. The power system is a steady-state balancesystem. The energy storage power station adjusts and buffers between various power sources andpower demand, which is equivalent to the role of “reservoir. The important role of energy storageincludes smoothing power fluctuations, cutting peaks and filling valleys, and improving power quality.With the future development trend of the energy storage industry is getting better and better, atthe same time, the explosion-proof pressure relief valve of the supporting accessories willincrease., the development of energy storage industry has the following advantages:

1, electrochemical energy storage industry rapid development, broad market spaceIn recent years, the global electrochemical energy storage market has entered a period of rapid growth.In 2019, China’s communications energy storage lithium battery shipments reached 6.0GWh, with anaverage annual growth of 88% from 2017 to2019. In the future,with the large-scale development ofglobal renewable energy and the continuous improvement of power system requirements,electrochemical energy storage technology has a broad application space in power system.2, supporting favorable policies will better open the market.At present, China’s auxiliary service market is still in the exploration period, the power marketmechanism that is conducive to energy storage to play the technical advantages has not yet beenformed, and the pricing and trading mechanism of various local policies on power auxiliary services hasnot yet been perfected. However, with the deepening of China’s power system reform and the release ofenergy storage policy, energy storage participation in power auxiliary services and user-side energystorage participation in power demand response will realize the value superposition of energy storagesystem, laying the foundation for its profitable commercial development.3, energy storage technology will further breakthroughenergy storage market depends on the innovation of energy storage technology to drive down the costand improve the performance. With the large-scale promotion and application of electrochemical energystorage, the performance and cost of battery systems have gradually become bottlenecks affecting therapid development of the industry.In the future, it is necessary to achieve technological breakthroughsin battery materials, manufacturing processes, system integration, operation and maintenance, andreduce Manufacturing and operating costs.
