An all-solid-state battery enabled by the incombustible and highly Li-ion conductive sulfide solid-state electrolyte, is recognized to be a strong candidate for next-generation of lithium-ion batteries. Intensive research efforts have been devoted to developing the well-suited sulfide electrolytes with outstanding performances. Although several types of sulfide electrolytes have achieved superionic conductivities with excellent deformability, the air-sensitive behaviors of them are detrimental to the large-scale production. Considerable efforts are in progress to tackle this issue via various strategies in recent years. This review provides an overview of several classes of promising sulfide solid electrolytes. The principle and strategies for improving the resistance of these sulfide electrolytes against air are thoroughly discussed. We also point out the major challenges that all-solid-state batteries and different types of sulfide electrolytes face for practical applications.
