Abstract: A method for manufacturing a battery includes (a) laminating an insulating layer on a part of at least one surface of at least one first collector, (b) laminating at least one power-generating element in which an electrode active material layer, a solid electrolyte layer, and a counter-electrode active material layer are laminated in this order and the at least one first collector on which the insulating layer is laminated such that the electrode active material layer covers the insulating layer, (c) cutting, in a laminating direction at a position where the insulating layer is divided, the at least one first collector on which the at least one power-generating element are laminated, and (d), before or after cutting the at least one power-generating element in the cutting (c), laminating a second collector on a surface of the at least one power-generating element that is opposite to the at least one first collector.

Abstract: A battery includes: a power generating element that includes at least one solid-state battery cell that includes a positive electrode, a solid electrolyte layer, and a negative electrode which are laminated; a first pressurizing member in contact with a first principal surface of the power generating element; a second pressurizing member in contact with a second principal surface of the power generating element, the second principal surface being opposite to the first principal surface. The first pressurizing member includes a first void. The second pressurizing member includes a second void. The insulating member includes a side surface portion that covers a side surface of the power generating element, and an extending portion that extends from the side surface portion into each of the first void and the second void.
