针对金属锂负极在恒电流充放过程中面临的SEI膜破裂和锂枝晶生长会极大降低电池的使用寿命和倍率性能，并且具有较大安全隐患的问题，分别从SEI膜设计、电解质改性和金属锂负极结构设计3个方面综述了相关研究进展，为今后高容量金属锂电池的研究提供了参考和思路。

During the constant current charging and discharging process,lithium metal anode may face risks of SEI film rupture and lithium dendrite growth,which can greatly reduce the service life and rate performance of the battery,and bring about huge hidden dangers.Relevant research progress is reviewed from three aspects,namely SEI film design,electrolyte modification and structure design of lithium metal anode,which provides references and ideas for the research of high-capacity lithium metal battery in the future.
