A power supply device is provided with: a battery block (10) in which a plurality of battery cells (1) are laminated in the thickness direction with a separator (2) therebetween; a pair of end plates (3) disposed on both end surfaces of the battery block (10); and a lacing strip (4) that is connected to the pair of end plates (3) and that fixes the battery block (10) in a pressurized state by means of the end plates (3). The separator (2) is formed by laminating an elastic body layer (5) and a plastic foaming body layer (6), and the deformation amount of the plastic foaming body layer (6) relative to the pressing force is larger than that of the elastic body layer (5) relative to the pressing force.
一种电源装置,其具有隔着隔板(2)沿厚度方向层叠多个电池单体(1)而成的电池块(10)、配置于电池块(10)的两端面的一对端板(3)、以及与一对端板(3)连结并借助端板(3)将电池块(10)固定为加压状态的束紧条(4)。隔板(2)通过层叠弹性体层(5)和塑料发泡体层(6)而成,该塑料发泡体层(6)的相对于按压力的变形量大于弹性体层(5)的相对于按压力的变形量。
