Perspective on powder technology for all-solid-state batteries: How to pair sulfide electrolyte with high-voltage cathode

Additionally, the integration of sulfide SEs and high-voltage cathodes is promising to achieve higher energy density. However, the incompatible interfaces between sulfide SEs and high-voltage cathodes have been one of the key factors limiting their applications.

Therefore, this review presents a critical summarization of the interfacial issues in all-solid-state lithium batteries based on sulfide SEs and high-voltage cathodes and proposes strategies to stabilize the electrolyte/cathode interfaces. Moreover, the future research direction of electrolyte/cathode interfaces and application prospects of powder technology in sulfide-based ASSLBs were also discussed.
