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.
由不可燃且锂离子传导性高的硫化物固态电解质实现的全固态电池，被认为是下一代锂离子电池的有力候选者。人们投入了大量研究精力来开发性能优异的合适硫化物电解质。尽管几种类型的硫化物电解质已实现具有出色可变形性的超离子电导率，但它们对空气敏感的特性不利于大规模生产。近年来，人们正在通过各种策略努力解决这个问题。本文综述了几类有前景的硫化物固体电解质。深入讨论了提高这些硫化物电解质抗空气能力的原理和策略。我们还指出了全固态电池和不同类型硫化物电解质在实际应用中面临的主要挑战。
