In the pursuit of next-generation energy storage systems, solid-state lithium metal batteries (SSLMBs) that can match both high-voltage cathodes and lithium metal anodes have attracted considerable attention in both industry and academia due to their high-energy density, enhanced safety, and cycle-life benefits. However, SSLMBs suffer from severe degradation of solid electrolytes (SEs) along with the continuously increasing cutoff voltage. Consequently, designing a compatible SE is crucial for high-voltage SSLMBs. In this review, the recent developments of high-voltage SSLMBs in the field of SEs are summarized, including their fundamental understanding, interfacial degradation mechanisms, and application prospects. Moreover, we specifically highlight the design principles needed to achieve intrinsic and extrinsic stability for SEs under high voltage. Finally, a summary of the existing challenges and perspectives on the high-voltage-stable SEs and SSLMBs are also discussed with the aim of guiding the development of state-of-the-art SEs for future high-energy and high-safety SSLMBs.

在追求下一代储能系统的过程中，能够同时匹配高压正极和锂金属负极的固态锂金属电池（SSLMBs）以其高能量密度、增强的性能等特点引起了工业界和学术界的广泛关注安全性和循环寿命优势。然而，SSLMBs 的固体电解质 (SEs) 严重退化，并且截止电压不断增加。因此，设计兼容的 SE 对于高压 SSLMB 至关重要。在这篇综述中，总结了 SEs 领域中高压 SSLMBs 的最新进展，包括它们的基本认识、界面退化机制和应用前景。而且，我们特别强调了在高压下实现 SE 的内在和外在稳定性所需的设计原则。最后，还讨论了高压稳定 SE 和 SSLMB 的现有挑战和前景的总结，旨在指导未来高能和高安全 SSLMB 的最先进 SE 的开发。
