Abstract: A battery of the present disclosure includes a power generation element. Each of the plurality of unit cells includes an electrode layer, a counter electrode layer, and a solid electrolyte layer arranged between the electrode layer and the counter electrode layer. The power generation element includes a first principal, a second principal opposite to the first principal, and a side surface connecting the first principal and the second principal. The side surface includes: a first inclined surface that connects to the first principal and forms an obtuse angle with the first principal; and a second inclined surface that connects to the second principal and forms an obtuse angle with the second principal. At least one of the first inclined surface and the second inclined surface is provided across two or more of the plurality of unit cells.

Abstract: A battery includes an electrode collector, two electrode active material layers, two solid electrolyte layers, two counter-electrode active material layers, and two counter-electrode collectors in this order, and includes a first insulating layer that covers side surfaces of the two counter-electrode collectors, the two counter-electrode active material layers, the two solid electrolyte layers, and the two electrode active material layers. A first region not covered with any of the two electrode active material layers is provided at ends of both principal surfaces of the electrode collector. A second region not covered with any of the two counter-electrode collectors is provided at an end of a principal surface of each of the two counter-electrode active material layers that faces toward a corresponding one of the counter-electrode collectors. The first insulating layer covers the second region. The electrode collector projects from an outer surface of the first insulating layer.

Abstract: A method for manufacturing a laminated battery is a method for manufacturing a laminated battery in which a plurality of unit battery cells each having a negative-electrode layer, a positive-electrode layer are laminated, and a solid electrolyte layer located between the negative-electrode layer and the positive-electrode layer. The method includes laminating the plurality of unit battery cells and collectively compressing, in a direction of laminating, the plurality of unit cells laminated in the laminating. In the laminating, the plurality of unit battery cells are laminated in such an arrangement that two unit battery cells located at both ends in the direction of laminating are both lower in degree of compression than a unit battery cell located between the two unit battery cells.

Abstract: A battery includes: a positive electrode current collector, a positive electrode active material layer, a solid electrolyte layer containing a solid electrolyte, a negative electrode active material layer, and a negative electrode current collector that are laminated in this order; and a sealing member. The battery has an opening hole penetrating the positive electrode current collector, the positive electrode active material layer, the solid electrolyte layer containing the solid electrolyte, the negative electrode active material layer, and the negative electrode current collector in a laminating direction and further includes a sealing member. In cross-sectional view perpendicular to the laminating direction, the sealing member is located between the opening hole and each of the positive electrode active material layer, the solid electrolyte layer, and the negative electrode active material layer.
