METHOD FOR PRODUCING SULFIDE GLASS OR SULFIDE GLASS CERAMIC CAPABLE OF CONDUCING LITHIUM ION, AND WHOLE SOLID TYPE CELL USING SAID GLASS CERAMIC

摘要

A method for producing a sulfide glass or a sulfide glass ceramic being capable of conducting a lithium ion, which comprises subjecting metallic lithium, simple sulfur and simple phosphorus as raw materials, which constitute the sulfide glass and the sulfide glass ceramic, to mechanical milling, to thereby convert them to a sulfide glass or a sulfide glass ceramic; and a whole solid type cell using a sulfide glass or a sulfide glass ceramic capable of conducting a lithium ion produced by the method as a solid electrolyte. The method allows the production of a sulfide glass and a sulfide glass ceramic exhibiting high electrocoduvtivity at room temperature from raw materials being easily available and non-expensive through an easy and simple way.
