Abstract:
To provide a power storage module capable of restraining occurrence of problems due to concentration of load on a part of a collector held by a frame body.SOLUTION: A power storage module includes multiple bipolar electrodes. Each of the multiple bipolar electrodes includes a collector having a plate shape extending in a direction intersecting the lamination direction, and having an outer peripheral edge part covered and held by a frame body placed around the bipolar electrode in the intersection direction, and a positive electrode layer provided on the first face of the collector, and located farther inside than the outer peripheral edge part in the intersection direction, and a negative electrode layer provided on the second face of the collector, and located farther inside than the outer peripheral edge part in the intersection direction. The collector is provided with the outer peripheral edge part, and an exposure part located between a region of the first face where the positive electrode layer is provided and a region of the second face where the negative electrode layer is provided, the exposure part is located between the frame body and the negative electrode layer in the intersection direction, and has a long portion longer than the interval of the frame body and the negative electrode layer in the intersection direction.SELECTED DRAWING: Figure 4
