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 an elastic body (5), and a plurality of rows of parallel ridges (21) and a plurality of rows of parallel grooves (22) are alternately arranged on the surface of the plate-shaped part (20) and on the opposite surface opposite to the battery cells (1), so that the cross-sectional shape is comb-shaped.
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)设为弹性体(5),在板状部(20)的表面且是与电池单体(1)相对的相对面交替地配置有多列平行凸条(21)和多列平行槽(22),从而使截面形状为梳齿状。
