An all-solid-state lithium battery with sulfur as positive electrode materials

An all-solid-state lithium battery was assembled with sulfur as positive electrode materials and with an inorganic solid electrolyte a-60Li(2)S(.)40SiS(2) (mol %). The all-solid-state lithium battery showed successive reversibility with large specific capacity. The specific capacity calculated on the base of the mass of sulfur was more than 1000 mA(.)h(.)g(-1).
