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 cell including: a pair of interconnectors for electrically connecting unit cells; a membrane-electrode assembly disposed between the interconnectors; a pair of current collectors, each of which includes an abutting surface abutting against a corresponding one of the electrode layers and a first base material surface being in contact with a corresponding one of the interconnectors and electrically connecting the corresponding of the electrode layers and the corresponding one of the interconnectors; and elastic bodies biasing the abutting surface of at least one current collector toward a corresponding one of the electrode layers. The elastic bodies includes: a second base material surface being in contact with the first base material surface; and an elastic body protruding portion supporting the abutting surface and protruding from the second base material surface toward the corresponding one of the electrode layers to bias the abutting surface toward the corresponding one of the electrode layers.
