The all-solid-state lithium battery based on sulfide-based electrolyte is promising for high-energy storage systems, but faces challenges in achieving stable interfaces with composite cathodes. Various strategies have been explored to address the impedance issues at the interfaces. Future developments need to focus on overcoming challenges in composite cathodes to achieve high performance in all-solid-state batteries.
All-solid-state lithium battery (ASLB) based on sulfide-based electrolyte is considered to be a candidate for the next-generation high-energy storage system. Despite the high ionic conductivity of sulfide solid electrolyte, the poor interfacial stability (mechanically and chemically) between active materials and sulfide solid electrolytes in composite cathodes leads to inferior electrochemical performances, which impedes the practical application of sulfide electrolytes. In the past years, various of strategies have been carried out to achieve an interface with low impedance in the composite cathodes. Herein, a review of recent progress of composite cathodes for all-solid-state sulfide-based lithium batteries is summarized, including the interfacial issues, design strategies, fabrication methods, and characterization techniques. Finally, the main challenges and perspectives of composite cathodes for high-performance all -solidstate batteries are highlighted for future development.
