Abstract: With the increasing maturity of large-scale electrochemical energy storage applications and the shortage of energy storage resources caused by the increase in the penetration rate of new energy in the future, the development of gigawatt-level electrochemical energy storage power stations is imminent. In view of the main problems and technical difficulties of gigawatt-level electrochemical energy storage power stations, the development process of gigawatt-level electrochemical energy storage power stations is summarized. On this basis, the key technical indicators, integrated structure and application scenarios of gigawatt-level electrochemical energy storage power stations are analyzed. Finally, the construction and development of gigawatt-level electrochemical energy storage power stations in the future are summarized and prospected.
