Abstract:
1. A nonaqueous-electrolyte battery comprising a positive-electrode active-material layer containing a Li-containing oxide; a negative-electrode active-material layer on which deposition of Li metal can occur; and a sulfide-solid-electrolyte layer disposed between these active-material layers, wherein the sulfide-solid-electrolyte layer includes a powder-formed layer formed on a positive-electrode-active-material-layer side of the sulfide-solid-electrolyte layer, and a dense-film layer formed on a surface of the powder-formed layer by a vapor-phase process, wherein the sulfide-solid-electrolyte layer includes an additional powder-formed layer, and the additional powder-formed layer is formed between the dense-film layer and the negative-electrode active-material layer, and wherein a dense-film-layer-side surface of the additional powder-formed layer has a surface roughness Rz of 1 μm or less.
