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

Abstract

Carbon-coated SiO (SiO-C) pelletized electrode without binder materials and solid electrolytes worked as negative electrode materials for sulfide-based all-solid-state batteries. The SiO-C pelletized electrode exhibited the high capacity (ca. 1340 mAh g⁻¹) for all-solid-state batteries using lithium-ion conducting sulfide-based solid electrolyte at room temperature. The SiO-C pelletized electrode containing sulfide solid electrolyte exhibited superior cycle stability compared to the SiO-C pelletized electrode. Their SiO-C pelletized electrodes are promising as high-performance negative electrodes for all-solid-state batteries.
