In actual use, when the battery 1 is expanded, the wider side surface is mainly expanded, so that a certain gap is left between the wider sides of the battery 1 during installation, and the separator 3 is arranged to prevent the batteries 1 from approaching each other due to the influence of external force. The buffer plate 4 is a bent plate shaped like a Chinese character 'ji', on one hand, the buffer plate 4 can limit the position of the battery 1; on the other hand, when the battery 1 expands, the buffer plate 4 can counteract the deformation of the battery 1, and the case 2 is prevented from being squeezed due to the expansion of the battery 1, so that the case 2 is prevented from being damaged.

Further, the battery pack further includes a heat dissipation plate 5, and the heat dissipation plate 5 is fixedly provided in the case 2 and abuts against the narrow side surfaces of the plurality of cells 1 in the same row.
