Abstract: Organic liquids are mostly used as an electrolyte system in commercial lithium-ion batteries. Currently organic liquids electrolytes have certain safety issues caused by the inflammability, explosiveness and leakiness. All solid state lithium ion battreies used inorganic solid electrolytes offer a fundamental solution to the safety issues of conventional lithium ion battreies containing organic electrolytes. The inorganic solid electrolyte has attracted much people's attention recently because of its great advantages: Inhibition the dentrite formation in lithium anodes, the high mechanical robustness, simplification the preparation technology of battery, reducing the manufacturing cost of the battery. This article presents a brief review of the researches on binary sulfide system, ternary sulfide system, preparation and modifications. The prospects of the solid electrolytes are also stated.

Key words: solid electrolyte, binary sulfide system, ternary sulfide system, modification, energy storage
