Lithium ion battery energy storage has gradually dominated, and 3.7v li-ion battery and echelonutilization have been excluded.
In recent years, the installed capacity of lithium battery energy storage has expanded year by year, from5.7GW in 2018 to 23.1GW in 2021,with an annual compound growth rate of 59%,and the proportion in new energy storage has increased year by year,from 86% to 95%.
According to our calculation, although the initial investment cost of li ion battery energy storages relatively high, its full life cycle cost is lower than that of pumped storage energy.
In the future, with the continuous reduction of the cost of lithium battery, its cost performance will be further improved.According to our calculation, the demand scale of energy storage lithium ion battery can reach 600 GWh by 2025.
In addition, according to the regulations of the National Energy Administration, ternary lithium batteries and cascade utilization batteries should not be used as energy storage batteries, and iron phosphate batteries become the mainstream technology route of energy storage batteries in the future.
