Abstract:

The development of electronic devices, such as portable electronics, electric vehicles and smart grids, brings new requirements and challenges to electrochemical energy storage system. Solid state lithium-sulfur batteries have attracted much attention for their high theoretical energy density and safety properties. Owning to high ionic conductivity and excellent interface contact, sulfide solid electrolytes are suitable for solid state lithium-sulfur batteries. This review summarizes the recent progress of solid state lithium-sulfur batteries with sulfide solid electrolytes. It focuses on the properties of sulfide solid electrolytes, the formation of efficient carrier pathways on the cathode side, and the stable lithium/electrolyte interfaces on the anode side. The future development directions of solid state lithium-sulfur batteries with sulfide solid electrolytes are also prospected.

Key words: lithium sulfur battery, solid electrolyte, ionic conductivity, sulfide, lithium metal anode
