Stress‐Regulated Li Plating in Hybrid Ag–Carbon/Carbon Nanofiber Anodes for Durable All‐Solid‐State Batteries
All‐solid‐state batteries (ASSBs) with Li‐metal or Li‐metal‐free anodes enable high energy density, yet high‐loading cathodes induce severe mechanical instability, leading to rapid cell failure. Herein, we identify stress accumulation caused by repetitive Li plating/stripping as a critical degradation origin in ASS...
