Abstract:
1. A battery module in which a plurality of cells are aligned, the battery module comprising: a holder having accommodation sections in which the plurality of cells are accommodated such that terminals of first electrodes are aligned at one side and terminals of second electrodes are aligned at the other side; a first electrode current collector plate which is provided to face terminals of first electrodes of the plurality of cells, and electrically connects the terminals of the first electrodes in parallel; and a second electrode current collector plate which is provided to face terminals of second electrodes of the plurality of cells, and electrically connects the terminals of the second electrodes in parallel; wherein a spacer made of an elastic member is disposed between the first electrode current collector plate and the cells, the spacer further includes an extended portion extending from the side at which the terminals of the first electrodes of the cells are aligned toward the terminals of the second electrodes of the cells along side surfaces of the cells, and an edge of the extended portion close to the terminals of the second electrodes touches the second electrode current collector plate.
