Lithium‐Rich Li2TiS3 Cathode Enables High‐Energy Sulfide All‐Solid‐State Lithium Batteries

“…In the late stage of charge, the Li + diffusivity recovers slightly because of the homogenization of the delithiated phase in the cathode. [ 59 ] During the discharge, the lowered Li + diffusivity caused by boundaries of lithiated and delithiated phases is alleviated by the increased open Li + channels in the regenerated nanocrystals that are the main contributor to the substantially accelerated Li‐ion diffusion after 40% DOD. Overall, the highly reversible structure and fast electrochemical kinetics of the LTS‐30 h electrode enable advanced ASSLBs with high reversible capacity and good cycling performance.…”
