All-solid-state Li-sulfur batteries with mesoporous electrode and thio-LISICON solid electrolyte

► All-solid-state battery with a composite cathode, sulfur/CMK-3, and solid electrolyte, thio-LISICON was studied. ► CMK-3 is a high ordered two-dimensional meso-porous carbon and provides a framework structure for the cathode composite. ► The sulfur/CMK-3 cathode exhibited high capacity and excellent cycling characteristics.
