Energy storage batteries focus on battery capacity, stability, and life, and consider battery module consistency, battery material expansion rate and energy density, and electrode material performance uniformity to achieve longer life and lower cost.

　　The cycle life of the energy storage battery is generally required to be greater than 3500 times.

　　From the perspective of application scenarios, energy storage batteries are mainly used in peak and frequency modulation power auxiliary services, renewable energy grid-connected, micro-grid and other fields.

　　In the communications field, 5G base stations are the core basic equipment of 5G networks. Macro base stations are generally used in conjunction with micro base stations. Since the energy consumption is several times that of the 4G period, a lithium battery energy storage system with higher energy density is required. Among them, macro base stations can be used Lithium iron phosphate battery acts as an emergency power source for the base station and assumes the role of peak shaving and valley filling. Therefore, power supply upgrades and replacement of lead-acid batteries with lithium iron phosphate batteries are the general trend.

　　For business models such as thermal power distribution and shared energy storage, system optimization and control strategies are also important factors that cause economic differences between projects.

　　Energy storage is a cross-discipline, and overall solution vendors who understand energy storage, power grids, and trade are expected to stand out in the subsequent competition.

　　There are two main types of participants in the energy storage system market: battery manufacturers and PCS (Power Conversion System) manufacturers. The battery manufacturers deploying energy storage batteries are represented by LG Chem, CATL, BYD, Zhilian New Energy, etc., and are expanding downstream based on the basis of battery cell manufacturing.

　　Zhilian New Energy focuses on the energy storage market, with a longer industrial chain, and can provide customers with integrated solutions for energy storage systems that match the products. The battery business of CATL and other manufacturers is still dominated by power batteries, and they are more familiar with electrochemical systems. Currently, they mainly provide energy storage batteries and modules, which are in the upper reaches of the industrial chain.

　　Looking at the corporate competition pattern of the global energy storage industry, after the energy storage industry is standardized, the concentration of production capacity is expected to further increase.
