Engineering a Fast Li + -Diffusion Secondary Phase in Sn Anodes for Low-Pressure All-Solid-State Batteries
Alloys are promising anode candidates for all-solid-state batteries (ASSBs) due to their high specific capacities and regulated interphase with the nonflowing solid-state electrolytes (SSEs). However, selection of alloys is constrained by low initial Coulombic efficiency (ICE), which often excludes candidates with hi...
