摘　　要：锂金属负极凭借高理论容量和低电化学电位,一直被誉为最具潜力的负极材料。然而,锂金属目前仍面临着锂枝晶不可控生长的风险,这严重影响了锂金属电池的循环寿命和安全性能,阻碍了其在实际生产中的应用。目前,改善锂金属负极性能的研究主要集中在SEI膜的调控、构建锂复合结构和引入固态电解质等3个方面。本文综述了多种策略在锂金属负极性能优化中的研究现状,展望了锂金属负极在未来储能领域的发展趋势。With its high theoretical capacity and low electrochemical potential,lithium metal anode has always been known as the most potential anode material.However,lithium metal is still facing the risk of uncontrolled growth of lithium dendrites,which seriously affects the cycle life and safety performance of lithium metal batteries,and hinders its application in actual production.At present,the research on improving the performance of lithium metal anode mainly focuses on the regulation of SEI film,the construction of lithium composite structure and the introduction of solid⁃state electrolyte.In this paper,the research status of various strategies in the performance optimization of lithium metal anode is reviewed,and the development trend of lithium metal anode in the field of energy storage in the future is prospected.
