Sulfur was investigated as positive electrode materials for all-solid-state lithium batteries with an inorganic solid electrolyte a-60Li(2)S.40SiS(2) (mol%). The sulfur (54 mass%) was ball-milled with metallic copper (42.8 mass%) and acetylene black (3.2 mass%) for 10 h and the obtained composite was used as the positive electrode materials of the solid-state battery. The composite worked as reversible positive electrode materials with a large electrochemical capacity. The capacity that was calculated on the base of the weight of sulfur was larger than 980 mAhg(-1). The all-solid-state lithium cell showed a successive reversibility with the large specific capacity.
