Properties of Carbon-coated SiO-C Negative Electrodes for Sulfide-type All-solid-state Batteries

Abstract

Carbon-coated SiO (SiO-C) sheet-type electrodes without sulfide-based solid electrolytes on a current collector worked as negative electrode materials for all-solid-state batteries. The SiO-C sheet-type electrodes exhibited the high capacity (ca. 1500 mAh g⁻¹), good cycle and high-rate discharge performance for all-solid-state batteries using sulfide solid electrolytes at room temperature. It is notice that SiO-C film electrodes are expected to promote new ionic-electronic conducting interface for sulfide-based solid electrolytes in all-solid-state batteries.
