摘要

作为下一代电池储能系统的关键部件，固态电池已引起广泛关注。Li10GeP2S12（LGPS）型固态电解质（SSE）因其优异的离子导电性和潜在的高温稳定性而受到研究人员的青睐。然而，LGPS 型固态电解质与电极之间的界面不良严重阻碍了 LGPS 全固态锂电池的商业化。本综述介绍了 LGPS 型固态锂电池的结构和锂离子传导机制，并讨论了与 LGPS 型固态锂电池/电极界面相关的挑战以及克服这些挑战的策略。为了提高界面兼容性，研究人员开发了改进和优化 LGPS 型 SSE 的可行方法。综述最后介绍了未来 LGPS 全固态锂电池的潜在研究方向和前景。

Interface engineering in LGPS-type solid-state electrolytes for all-solid-state lithium batteries

As key components of next-generation battery energy storage systems, solid-state batteries have attracted widespread attention. Li₁₀GeP₂S₁₂ (LGPS)-type solid-state electrolytes (SSEs) are favored by researchers owing to their excellent ionic conductivity and potential high-temperature stability. However, the poor interface between LGPS-type SSEs and electrodes has seriously hindered the commercialization of LGPS all-solid-state lithium batteries. This review introduces the structure and Li-ion conduction mechanisms of LGPS-type SSEs and discusses the challenges related to LGPS-type SSEs/electrode interfaces, along with strategies for overcoming these challenges. To improve the interface compatibility, researchers have developed feasible methods for improving and optimizing LGPS-type SSEs. The review concludes with potential research directions and prospects of future LGPS all-solid-state lithium batteries.
