摘　　要：无机固体电解质又称快离子导体,其中玻璃态硫化物快离子导体具有离子电导率高,电子电导率低,活化能小,机械强度高等优点。对一些典型的Li2S-P2S5及Li2S-Si S2基硫化物固体电解质进行了分类讨论,对它们的性能结构进行评述。在总结二元Li2S-P2S5及Li2S-Si S2固体电解质的结构和性能的基础上,分析了其它掺杂剂对此二元固体电解质导电性的影响。Super ionic conductor sulfide glasses of inorganic solid state electrolytes called super ionic conductors have high ionic conductivity, low electronic conductivity and activation energy, high mechanical strength and so on. Typical Li2S-P2S5 and Li2S-SiS2 based sulfide solid state electrolytes were classified and discussed. The properties and structural characteristics were reviewed. On the basis of concluding properties and structural characteristics of binary Li2S-P2Ssand Li2S-SiS2 solid state electrolytes, the influence of other dopants on conductivity of binary solid state electrolytes was analyzed.
