Abstract: All-solid-state lithium ion batteries utilize solid state electrolytes to overcome the safety issues of liquid electrolytes, becoming the most promoting candidate for electric vehicle and large-scale stationary-type distributed power sources. There is an urgent demand for all solid state lithium ion batteries with high energy and power densities and longevity. Materials hold the key to fundamental and practical advances in all-solid-state lithium ion batteries. Most studies have been focused on exploration and preparation of solid electrolytes with high ambient temperature ion conductivity as well as cathode and anode with high energy density, and optimization of interfacial compatibility between electrode and solid electrolyte. This paper is a comprehensive review of the key materials for all-solid-state lithium ion batteries: Various important advances of new solid electrolyte, cathode and anode made in research and practical application, the modification methods to improve the interfacial behavior, and the further development of materials and interfacial issues, which lay a foundation for the analysis of commercial applications prospect of all-solid-state lithium ion batteries.

Key words: all-solid-state lithium-ion battery, solid-state electrolyte, cathode, anode, interfacial compatibility
