Development of Electrochemical Energy Storage Technology

As an important component of the new power system, electrochemical energy storage is crucial for addressing the challenge regarding high-proportion consumption of renewable energies and for promoting the coordinated operation of the source, grid, load, and storage sides.As a mainstream technology for energy storage and a core technology for the green and low-carbon transformation of existing energy structures, the electrochemical energy storage technology still needs to be further developed to adapt to the challenges brought about by the rapid growth of energy storage scale and the increasingly complex energy storage system.This study analyzes the demand for electrochemical energy storage from the power supply, grid, and user sides, and reviews the research progress of the electrochemical energy storage technology in terms of strategic layout, key materials, and structural design.Moreover, it clarifies the development trend of electrochemical energy storage technologies and identifies the problems such as inconsistency in product specifications, deficiency in detection platforms, and disconnection between theory and practice.Future efforts need to focus on the following directions: key materials with high performance, high safety, and low cost;收稿日期：2023-07-28；修回日期：2023-10-30 通讯作者： * 陈人杰，北京理工大学材料学院教授，研究方向为高比能、高安全二次电池材料及器件，特种功能电源，新型功能复合电解质， 二次电池资源化再生等；E-mail: chenrj
