Stable Catholyte Interface Enables Practical Operation of Sulfide‐Based All‐Solid‐State Li Metal Batteries (Adv. Energy Mater. 7/2026)

All-Solid-State Batteries In article number e03019, Soojin Park, Sang-Min Lee, and co-workers report a fluorocarbon-terminated self-assembled-monolayer strategy that forms a chemically inert surface on LPSCl, enabling dry room-compatible slurry processing. Stabilized catholyte enhances chemical/electrochemical robustness, supports high-rate cycling under low pressure, and achieves long-term stability in thin-Li full cells, advancing scalable all-solid-state batteries.
