摘要： A load applicator includes an elastic mechanism including elastic bodies, a first member configured to move in accordance with contraction of power storage cells, a second member provided opposite to the first member across the elastic mechanism, a switching device, and a restriction member. The elastic mechanism has a first form wherein a first restraint load is applied to a power storage module when the power storage module expands by a first dimension, and a second form wherein a second restraint load larger than the first restraint load is applied to the power storage module when the power storage module expands by the first dimension. The switching device performs an operation switching from the first form to the second form in a case where a restraint load smaller than the first restraint load is applied to the power storage module when the power storage module expands by the first dimension.

摘要： A secondary battery includes a positive electrode, a negative electrode, a single positive electrode terminal formed in a flat plate shape, a single negative electrode terminal formed in a flat plate shape, a holder holding the single positive and negative electrode terminals, and a laminate exterior body. The single positive and negative electrode terminals each have a single protruding portion protruding from the laminate exterior body in one direction. An insulating plate is arranged between main side surfaces of the single protruding portions of the terminals. On one side of the insulating plate in a facing direction, only the single protruding portion of the positive terminal protrudes from the laminate exterior body, and on the other side of the insulating plate in the facing direction, only the single protruding portion of the negative terminal protrudes from the laminate exterior body.

摘要： A secondary battery includes an electrode, a positive electrode current collector, a negative electrode current collector, a positive electrode terminal, a negative electrode terminal, and an insulating plate. The positive electrode terminal and the negative electrode terminal each have a main side surface and a sub side surface having an area smaller than that of the main side surface. The positive electrode terminal and the negative electrode terminal are arranged so that the main side surface of the positive electrode terminal and the main side surface of the negative electrode terminal face each other. The insulating plate is arranged between the main side surface of the positive electrode terminal and the main side surface of the negative electrode terminal.
