Abstract: A battery includes an electrode layer, a counter electrode layer, which is a counter electrode for the electrode layer, and a solid electrolyte layer between the electrode layer and the counter electrode layer. The solid electrolyte layer has a first region containing a first solid electrolyte material and a second region containing a second solid electrolyte material. The first region is positioned within a region where the electrode layer and the counter electrode layer face each other. The second region is positioned on an outer peripheral side of the region where the electrode layer and the counter electrode layer face each other, and is in contact with the first region. The first region includes a first projecting portion that projects outward from a region where the electrode layer and the counter electrode layer face each other, and the second region covers the first projecting portion.

Abstract: A battery includes: an electrode layer; a counter electrode layer, which is a counter electrode for the electrode layer; a solid electrolyte layer between the electrode layer and the counter electrode layer; and an electrode current collector electrically coupled to the electrode layer. The solid electrolyte layer includes a first region containing a first solid electrolyte material and a second region containing a second solid electrolyte material. The first region is positioned within a region where the electrode layer and the counter electrode layer face each other. Moreover, a second density, which is of the second solid electrolyte material in the second region, is higher than a first density, which is of the first solid electrolyte material in the first region.

Abstract: A battery includes a first insulator, a first electrode layer, and a first counter-electrode layer. The first counter-electrode layer is a counter electrode for the first electrode layer. The first insulator includes a first electrolyte portion, a second electrolyte portion, and a first bent portion. The first bent portion is positioned between the first electrolyte portion and the second electrolyte portion. The first electrode layer is disposed in contact with the first electrolyte portion. The first counter-electrode layer is disposed in contact with the second electrolyte portion. The first insulator is bent at the first bent portion, and thereby the first electrode layer and the first counter-electrode layer are positioned facing each other.
