A power storage module includes an electrode laminate including a plurality of bipolar electrodes which are laminated and a sealing body sealing a space between a pair of the bipolar electrodes adjacent to each other in a laminating direction among the plurality of bipolar electrodes in the electrode laminate. Each of the plurality of bipolar electrodes includes an electrode plate. The sealing body includes a group of primary sealing bodies each provided at an edge portion of the electrode plate and a secondary sealing body. The secondary sealing body includes a first resin portion that is provided along a side surface of the electrode laminate extending in the laminating direction and bonds the group of primary sealing bodies, and a second resin portion covering the first resin portion.

Power storage module and method for manufacturing power storage module

A power storage device includes a plurality of laminated power storage modules, a flow path member disposed in contact with the power storage modules and having flow paths for allowing a cooling medium to flow along a first direction intersecting a laminating direction of the power storage modules, a pair of restraining plates disposed to sandwich the power storage modules and the flow path member in the laminating direction, fastening members applying a restraining load to the power storage modules and the flow path member via the pair of restraining plates by fastening the restraining plates to each other, and a lead-in duct disposed at one end portion of the flow path member in the first direction and leading the cooling medium into each of the flow paths.

Power storage device

A battery module includes an electrode laminate including a plurality of electrodes that are laminated, and a sealing body sealing a side surface of the electrode laminate. The sealing body is provided with a communication hole communicating an internal space between the electrodes adjacent in a laminating direction in the electrode laminate. The communication hole includes an opening end on an outer surface of the sealing body. A length of the opening end in the laminating direction is longer than a length of the internal space in the laminating direction.
