摘　　要：本文综述了金属锂二次电池中提高锂负极性能的研究进展。分别介绍了以下改性方法:对金属锂表面进行预处理,使其表面预先形成性能良好的固体电解质界面膜,或直接在其表面制备保护膜;在电解液中加入添加剂对锂电极进行表面改性;采用新型有机溶剂、离子液体、聚合物电解质、玻璃态固体电解质、塑晶固体电解质等电解质体系提高界面相容性;改进金属锂电极的制备工艺,如制备金属锂粉末多孔电极和电沉积锂电极、制备全固态薄膜锂电池以及利用物理方法处理锂电极。并在此基础上对今后的发展趋势进行了展望。The research progress for improving the properties of lithium metal electrode in rechargeable lithium metal batteries is reviewed. The treatment methods are introduced respectively as follow： either making surface pretreatment on lithium metal, to form better solid electrolyte interface in advance, or producing the protecting coating directly; adding additives in electrolyte to improve the surface properties; improving the interfacial compatibility by applying new type organic solvent, ionic liquid, polymer electrolyte, glass-based solid electrolyte and plastic crystal solid electrolyte as the electrolyte systems; improving the fabrication process of lithium electrode, such as lithium powder electrode, electrodeposited lithium electrode and all solid-state thin film lithium battery as well as utilization of physical methods. The future development in the research is also prospected.
