Electrolyte‐free cathode design for solid‐state batteries demonstrated with bifunctional Li2VCl4
The “electrolyte‐free” cathode design is demonstrated by utilizing the ion‐conducting active material Li2VCl4. This design is exclusively viable within all‐solid‐state battery configurations, where both active materials and electrolytes exist in the solid state.
