Original Abstract Submitted
The bipolar battery module of the present disclosure has a structure in which a plurality of cells is stacked in a laminating direction of the bipolar electrodes. Each of the plurality of cells includes an internal space in which an electrolytic solution is accommodated between two positive-negative electrode foil adjacent to each other in the laminating direction. In a part of the outer peripheral part of each cell, a liquid injection opening for injecting an electrolytic solution into the internal space is formed by the sealing member. The liquid injection opening in at least a part of the cells has a shape widened to the adjacent cell side by disposing the peripheral edge part of at least one of the positive-negative electrode foil of the two positive-negative electrode foil so as to be offset to the adjacent cell side.
