In a power storage module, a side surface of an electrode laminate body has a welded layer where first sealing portions adjacent in a lamination direction are welded. A sealing body has: a side surface (opening wall) provided with a through hole communicating with an internal space; and side surfaces (non-opening walls) lacking the through hole. When viewed from the lamination direction, a width of the welded layer at the opening wall is smaller than a width of the welded layer at the non-opening wall.

Power storage module

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.

Electricity-storage module manufacturing method and electricity-storage module

A power storage moduleaccording to a first aspect includes: a laminated bodyin which bipolar electrodesincluding an electrode plate, a positive electrode, and a negative electrode, are laminated; a frame bodyprovided with an openingcommunicated with a plurality of internal spaces V; and a pressure adjustment valveconnected to the opening. The pressure adjustment valveincludes a base memberconnected to the openingand provided with a plurality of communication holesrespectively communicated with the plurality of internal spaces V, a valve bodyarranged to shut opening endsof the plurality of communication holes, and a cover memberpressing the valve bodyagainst the base member

Power storage module and method for manufacturing power storage module

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.
