摘要全固态锂电池因其高安全性和能量密度而受到越来越多的关注。在所有相应的固体电解质中，硫化物电解质被认为是最有前途的离子导体，由于高的离子电导率。尽管如此，在ASSLB的应用中仍然存在许多挑战，包括硫化物电解质的稳定性、硫化物电解质与氧化物电极之间的复杂界面问题以及不稳定的阳极界面。虽然氧化物阴极由于高稳定性和工业化程度而仍然是最可行的电极材料，但是硫化物电解质与氧化物阴极的匹配对于ASSLB的商业使用是具有挑战性的。在此基础上，本综述将介绍基于硫化物电解质和氧化物阴极的新兴ASSLB的概述，并强调关键性能，如兼容的电解质/电极界面。并结合硫化物电解质ASSLB目前面临的挑战和机遇，讨论了可能的研究方向和前景。
AbstractAll-solid-state lithium batteries (ASSLBs) have attracted increasing attention due to their high safety and energy density. Among all corresponding solid electrolytes, sulfide electrolytes are considered to be the most promising ion conductors due to high ionic conductivities. Despite this, many challenges remain in the application of ASSLBs, including the stability of sulfide electrolytes, complex interfacial issues between sulfide electrolytes and oxide electrodes as well as unstable anodic interfaces. Although oxide cathodes remain the most viable electrode materials due to high stability and industrialization degrees, the matching of sulfide electrolytes with oxide cathodes is challenging for commercial use in ASSLBs. Based on this, this review will present an overview of emerging ASSLBs based on sulfide electrolytes and oxide cathodes and highlight critical properties such as compatible electrolyte/electrode interfaces. And by considering the current challenges and opportunities of sulfide electrolyte-based ASSLBs, possible research directions and perspectives are discussed.Graphic Abstract
