This review compiles the fundamental principles, latest progress, and effective strategies for improving the chemical stability and compatibility of sulfide solid electrolyte (S-SE) based all-solid-state batteries (ASSBs). It highlights the importance of understanding the chemical stability of S-SEs towards air and their compatibility with solvents and binders, and presents encouraging demonstrations on improving their compatibility. Challenges, future directions, and perspectives on improving the chemical stability of S-SEs are also discussed.
Sulfide solid electrolyte (S-SE) based all-solid-state batteries (ASSBs) have received particular attention due to their outstanding ionic conductivity and higher energy density over conventional lithium-ion batteries. Nevertheless, their chemical instability toward air and their poor compatibility with solvents and binders are significant factors that impede the commercialization of S-SE-based ASSBs. This review aims to compile fundamental principles about the chemical stability of S-SEs and strategies designed to fabricate sulfide-based high energy density practical ASSBs covering their air stability and compatibility in slurry-based processes. Firstly, fundamental principles about the chemical stability of S-SEs towards air and their compatibility with solvents and binders are highlighted. Moreover, characterization techniques are examined to better understand the chemical stability of S-SEs. Secondly, the latest progress and effective strategies to improve the stability and compatibility of S-SEs are summarized. Encouraging demonstrations on improving the compatibility of S-SEs with solvents and binders are exemplified. Finally, challenges, future directions, and our perspectives on improving the chemical stability of S-SEs are presented.
