Abstract: Due to its advantages of high energy density and low cost, lithium sulfur battery has become a potential choice for electric vehicles and new energy storage devices. Anode protection has become a hot topic in recent years. By optimizing the anode, lithium dendrites can effectively be alleviated which can solve the problem of battery cycle life decreasing. In this paper, the strategy of anode protection for lithium sulfur battery was introduced from the aspects of electrolyte additive and anode structure design, and the mechanism of action was briefly described. Finally, the strategy development of lithium sulfur battery anode protection was prospected.

Key words: Lithium sulfur battery, Anode protection, Electrolyte additive, Li?rich alloy, 3D porous structure
