Abstract:
1. A method for producing a nonaqueous-electrolyte battery including a positive-electrode active-material layer, a negative-electrode active-material layer, and a sulfide-solid-electrolyte layer disposed between these active-material layers, the method comprising: a step of preparing a positive-electrode body including a positive-electrode active-material layer including a powder-molded body, and a positive-electrode-side solid-electrolyte layer that is amorphous and formed on the positive-electrode active-material layer by a vapor-phase process; a step of preparing a negative-electrode body including a negative-electrode active-material layer including a powder-molded body, and a negative-electrode-side solid-electrolyte layer that is amorphous and formed on the negative-electrode active-material layer by a vapor-phase process; and a step of bonding together the positive-electrode body and the negative-electrode body by subjecting the electrode bodies being arranged such that the solid-electrolyte layers of the electrode bodies are in contact with each other, to a heat treatment under application of a pressure to crystallize the positive-electrode-side solid-electrolyte layer and the negative-electrode-side solid-electrolyte layer.
