Cover Story: Sulfide solid-state electrolytes are important components for the development of high-performance all-solid-state batteries, because of their high ionic conductivity and deformability. However, significant challenges still remain. They form unstable interfaces and interphases in contact with electrodes, leading to battery performance degradation. In this review article, we provide an overview of the key issues and recent progress on interfacial instabilities in sulfide solid-state electrolyte systems, from the three points of view as follows: (i) Interfaces/interphases with Li metal anode, (ii) Li-dendrite penetration, and (iii) Interfaces/interphases in cathode composite. Furthermore, we provide insights into the potential directions of future research in this field. View this paper.
