摘　　要：全固态锂电池兼具安全性和高能量密度,作为下一代储能器件备受关注.硫化物固态电解质具有锂离子电导率高、晶界电阻低、机械延展性好等优点,作为最具商业化潜力的固态电解质,引起了产业界和科研单位的广泛兴趣.但是硫化物固态电解质较差的空气稳定性导致其制备以及后续组装的硫化物固态全电池需要在氩气保护的环境下进行操作,使得生产成本居高不下,严重制约其产业化的步伐.本文对硫化物固态电解质空气稳定性的相关研究包括空气稳定性的研究方法和衰减反应机制进行详细的梳理和客观分析,并提炼出提高硫化物固态电解质空气稳定性相应的策略与方法.Because of the safety and high energy density,all-solid-state lithium batteries have attracted much attention as the next-generation energy storage device.The sulfide solid electrolyte has the advantages of high lithium ion conductivity,low grain boundary resistance,and good mechanical ductility.As the most promising solid electrolyte with commercial potential,it has aroused wide spread interest in industry and scientific research institutions.However,due to the poor air stability of the solid sulfide electrolyte,the preparation and subsequent assembly of the solid sulfide battery need to be carried out under the protection of argon gas which makes its production cost high,which severely restricts its industrialization.In this paper,the research method and the attenuation reaction mechanism of the air stability of sulfide solid electrolyte,as well as the strategies to improve it are introduced.
