Abstract: A power storage device includes an electrode body, an electrode terminal connected to the electrode body, and an exterior body that seals the electrode body. The exterior body is configured from a film-like exterior member and includes a first sealing portion joined to the exterior member in a state where the exterior member envelops the electrode body. The exterior member includes a barrier layer. The power storage device has a resin film for a power storage device disposed at least partially inwards of the barrier layer. The resin film for a power storage device includes at least one among a water absorbent and a gas absorbent.

Abstract: This lid body is used in an electric power storage device, the electric power storage device including: an electrode body; an electrode terminal electrically connected to the electrode body; and an outer packaging film wrapped around the electrode body so as to have an opening, the lid body being located in the opening and including a first part and a second part having the electrode terminal interposed therebetween so as to be able to input and output electric power via the electrode terminal.

Abstract: A power storage device comprising: an electrode body that includes electrodes; a current collector that extends from the electrodes; an electrode terminal that is electrically connected to the electrode body via the current collector; an exterior film that is wrapped around the electrode body in such a manner as to have an opening; and a lid body that is disposed in the opening, wherein the lid body covers at least a part of the current collector.

Abstract: A power storage device includes an electrode body, and an exterior body for sealing the electrode body. The exterior body includes an exterior film for wrapping the electrode body so as to have a projection section that projects farther outward relative to the electrode body, and a seal section sealed by bonding mutually facing surfaces of the exterior film, and includes a projection seal section formed at the projection section, and a back-lining seal section that extends in a direction intersecting the direction in which the projection seal section extends in plan view.

Abstract: This power storage device includes an electrode body and an exterior body sealing the electrode body, wherein: the exterior body includes an exterior film wound on the electrode body so as to have an opening, a lid disposed in the opening, a first sealing part where mutually facing surfaces of the exterior film are sealed, and a second sealing part where mutually facing surfaces of the lid and the exterior film are sealed; and the sealing strength of the second sealing part is 40 N/15 mm or higher.

Abstract: A lid is used in an exterior body of an electricity storage device, wherein: the exterior body includes an exterior film which is wound around an electrode body so as to have an opening portion; and the lid is disposed in the opening portion and includes a lid seal portion that is sealed with the exterior film, and a projecting portion that projects from the lid seal portion.

Abstract: A first packaging material includes at least one layer located in both a first region and a second region. A second packaging material includes at least one layer located in both the first region and the second region. The hole includes a proximate position where the distance between the hole and the outer edge of the pouch in a center-of-gravity direction is shortest, the center-of-gravity direction being a direction in which a center-of-gravity line passing through the center of the pouch and the center of the hole extends. A communication part is connected with the hole at a position that is spaced apart from the proximate position in a direction orthogonal to the center-of-gravity direction. The outline of the communication part that extends from the hole to the outer edge includes a first line and a second line. The first line is located closer to the proximate position than is the second line.

Abstract: To suppress damage such as the formation of holes and wrinkles in laminated bodies constituting a bag. A bag having a storage section includes: laminated bodies that include a sealant film positioned on an inner surface of the bag and at least one plastic film positioned on an outer surface side of the sealant film; and a seal section where inner surfaces of one pair of laminated bodies are joined together. The seal section has an outer edge seal part that is positioned along an outer edge of the bag, and a steam-releasing seal part that is positioned closer to a center point side of the storage section than the outer edge seal part and peels off due to an increase in pressure in the storage section. The steam-releasing seal part peels off when the pressure in the storage section is 130 kPa or lower.

Abstract: To provide a PTP blister sheet exhibiting a high adsorption effect over prolonged periods, and a PTP blister pack formed from it. A PTP blister sheet having at least a gas barrier layer and an odor adsorption layer, wherein the odor adsorption layer comprises a heat-sealable resin containing an odor adsorption agent, and the odor adsorption agent is formed by a chemical adsorption agent supported on an inorganic porous body, and a PTP blister pack formed from it.

Abstract: A first packaging material includes at least one layer located in both a first region and a second region. A second packaging material includes at least one layer located in both the first region and the second region. An outline of a communication part that extends from the hole to the outer edge of the pouch includes a first line and a second line. The communication part includes a first portion and a second portion. The first position includes a portion where the first line and the second line have a spacing from each other that decreases with increasing distance from the outer edge of the pouch toward the hole. The second portion is located between the first portion and the hole, and includes a portion where the first line and the second line have a spacing from each other of less than or equal to 2.0 mm.
