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-60Li2S·40SiS2 (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.
