<p>The disclosed secondary battery assembly has: a secondary battery formed by enclosing a coiled electrode in a flat, square case; a contact member that is partially in contact with the surface that has the largest surface area (hereafter, the compressed surface) among the exterior surfaces of the secondary battery; and a restraining member that restrains the secondary battery and the contact member. In the secondary battery assembly, due to restraint by the restraining member, the contact member partially compresses the compressed surface. The contact member has multiple contact units, which are provided separately and are in contact with the compressed surface, and multiple connection units, which connect the multiple contact units to each other. The contact units are formed and positioned in such a manner that the contact units: are formed extending from the connection units towards the compressed surface; more strongly compress the compressed surface at offset regions on both sides, which correspond to points removed from the centre of the coiled electrode in the coil axis direction; and more weakly compress the compressed surface at central regions between the offset regions on both sides, which correspond to points more central to the coil axis direction of the coiled electrode.</p> |
