All-in-one cathode design for all-solid-state batteries

The development of safer, cheaper and more durable all-solid-state batteries demands a fundamental rethinking of composite cathode design. All-in-one cathode materials that integrate ionic conductivity, electronic conductivity and redox activity within a single phase redefine battery architecture by unifying electrochemical roles in one material.
