Abstract

All-solid-state lithium–sulfur batteries were fabricated using composite electrodes incorporating sulfur, carbon replica, and a solid electrolyte. Novel liquid-phase mixing contributed to improving electrochemical properties through solid-electrolyte penetration into the mesopores of the carbon replica. Combined mechanical and liquid-phase mixing realized a solid-state battery with high electrochemical performance comparable to a liquid battery system. A discharge capacity in excess of 1500 mAh g–1 and a high Coulombic efficiency of about 100% were demonstrated at an applied pressure of 213 MPa. The novel sulfur-electrode fabrication method enhances battery performance, since the ionic conduction pathway in the composite electrode is increased.
