Abstract
Provided are a nonaqueous-electrolyte battery in which short circuits between the positive- and negative-electrode layers can be suppressed with certainty and a method for producing the battery. A nonaqueous-electrolyte batteryincludes a positive-electrode active-material layercontaining a Li-containing oxide; a negative-electrode active-material layeron which deposition of Li metal can occur; and a sulfide-solid-electrolyte layer (SE layer)disposed between these active-material layersand. The SE layerof the nonaqueous-electrolyte batteryincludes a powder-formed layerand a dense-film layerformed on a surface of the powder-formed layerby a vapor-phase process. In the nonaqueous-electrolyte battery, the powder-formed layeris formed by a compression-molding process on a positive-electrode body including the positive-electrode active-material layerand the dense-film layeris then formed by a vapor-phase process on the positive-electrode body that is provided with the powder-formed layerand serves as a substrate.
