Abstract: An assembled battery has a battery block configured by stacking a plurality of single batteries, and fixing components fixing the plurality of the single batteries. The fixing components include a pair of end plates disposed at both ends in a stacked direction of the plurality of the single batteries, and a metal band making the plurality of the single batteries in a compressed state by coupling end parts of the pair of the end plates each other. Each of the pair of the end plates has a peripheral part and a central part. The pair of the end plates respectively contact both end single batteries located at both ends in the stacked direction at the peripheral parts, and are respectively separated from both end single batteries at the central parts.

Abstract: To provide a battery pack capable of taking out battery cells by disassembling the battery pack easily for recycling the battery cells in a battery pack using plural high-capacity lithium secondary battery cells. The battery cells are fixed by a cell holder and are housed inside a case in a state where both electrodes are sandwiched by a positive-electrode current collecting plate and a negative-electrode current collecting plate, and springs are arranged above and under the plates. There are claws on side surfaces of the case, which can temporarily fix the springs to the current collecting plates at the time of assembly and prevents the case from being ejected suddenly when a fastener is released at the time of disassembly, as a result, assembly/disassembly can be easily performed.

Abstract translation: 为了提供能够通过拆卸电池组而容易地取出电池单元的电池组，用于使用多个大容量锂二次电池单元再循环电池组中的电池单元。 电池单元由电池座固定，并且在两个电极被正极集电板和负极集电板夹持的状态下容纳在壳体内，弹簧布置在板的上方和下方。 在壳体的侧表面上有爪，其可以在组装时临时将弹簧固定到集流板上，并且在拆卸时防止紧固件被释放时突然弹出壳体，结果是组装 /拆卸可以轻松执行。
