Reduction of external pressure on all‐solid‐state battery using SnO2‐embedded porous carbon by CNT assistance

Abstract All‐solid‐state batteries (ASSBs) using non‐flammable inorganic solid electrolyte are expected as a safety energy storage system that exhibits a high energy density. Since external pressure is required to maintain stable interface between active materials and solid electrolyte, the pressure...
