Title: POWER STORAGE MODULE AND MANUFACTURING METHOD FOR POWER STORAGE MODULE
Abstract:
Provided is a power storage module comprising a cylindrical first seal member provided on the outside of a plurality of bipolar electrodes in a direction intersecting the stacking direction of the plurality of bipolar electrodes, and a second seal member provided on the outside of the first seal member in the direction intersecting the stacking direction. The first seal member has a plurality of frames provided between electrode plates that are adjacent in the stacking direction. Each of the frames includes a seal part overlapping with the peripheral edges of the electrode plates in the stacking direction, and a projecting part projecting outwards from the electrode plates in a direction intersecting the stacking direction. A gap is formed between projecting parts adjacent to each other in the stacking direction, and a part of the second seal member is inserted in the gap.
