In order to smoothly absorb the expansion of a battery cell which is secured in a pressurized state, a power supply device is equipped with: a battery block obtained by layering a plurality of battery cells (1) with a separator (2) interposed therebetween in the thickness direction; a pair of end plates positioned on both end surfaces of the battery block; and a binding bar which is connected to the pair of end plates and secures the battery block in a pressurized state via the end plates. The separator (2) is equipped with a heat-insulating sheet (5) and an elastic layer (6) layered on the surface of the heat-insulating sheet (5), said elastic layer (6) having: an elastic projecting part (6a) which is partially adhered to the case surface of the battery cell (1) and deforms due to the expansion of the battery cell (1); and a deforming space (7) in which the elastic projecting part (6a) moves in the outer-peripheral direction, which is aligned with the pressing direction, when pressed upon by the battery cell (1).

    为了顺畅地吸收被固定为加压状态的电池单体的膨胀,电源装置具有隔着隔板(2)沿厚度方向层叠多个电池单体(1)而成的电池块、配置于电池块的两端面的一对端板、以及与一对端板连结并借助端板将电池块固定为加压状态的束紧条。隔板(2)具有绝热片(5)以及层叠于绝热片(5)的表面的弹性层(6),弹性层(6)具有与电池单体(1)的壳体表面局部地紧密贴合并且在电池单体(1)的膨胀的作用下发生变形的弹性突出部(6a)、以及供弹性突出部(6a)被电池单体(1)按压而沿着与按压方向正交的外周方向移动的变形空间(7)。
