Abstract: A power storage device includes: a module stacked body including a plurality of power storage modules stacked in a first direction and having a first side surface extending in the first direction and a second direction orthogonal to the first direction and a second side surface adjacent to the first side surface and extending in the first direction and a third direction orthogonal to the first side surface and the second direction; a first restraint plate and a second restraint plate stacked on both sides of the module stacked body in the first direction and applying a restraint load to the module stacked body in the first direction; a wiring connected to the module stacked body; and a guide member coupled to the first restraint plate and the second restraint plate and disposing the wiring on the first side surface.

Abstract: A method for manufacturing an electricity-storage module includes: preparing a stacked body and first sealing portions; processing an extension portion of one or more first sealing portions included in an outer edge portion in a stacking direction of the stacked body so that an extension portion length of the one or more of first sealing portions becomes shorter than a length of the extension portions of the first sealing portions which are not included in the outer edge portion; and forming a second sealing portion that is provided at the periphery of the first sealing portions when viewed from the stacking direction and covers at least parts of outer surfaces of the first sealing portions located at stacking ends of the stacked body in the stacking direction by injection molding in which a resin material is caused to circulate in a mold frame.

Abstract: A power storage module includes a laminate constituted of a plurality of laminated bipolar electrodes, each of the bipolar electrodes including an electrode plate, a positive electrode provided on one surface of the electrode plate, and a negative electrode provided on the other surface of the electrode plate, wherein a plurality of internal spaces is formed between the bipolar electrodes adjacent to each other in the laminate; a frame body holding an edge portion of the electrode plate and provided with an opening communicating with at least one of the plurality of internal spaces; and a pressure regulating valve attached to the frame body.
