A power storage module includes an array including power storage devices each having first and second surfaces opposite to each other in a first direction, a first restraint member facing the first surface of each power storage device, and a second restraint member facing the second surface of each power storage device. Dimensions of the power storage devices in a second direction perpendicular to the first direction are larger than respective dimensions of the power storage devices. The power storage devices are arranged in a third direction perpendicular to the first and second directions. The first restraint member extends in the third direction and restrains the array in the third direction. The second restraint member extends in the third direction and restrains the array in the third direction. At least one of the first and second restraint members has a hole therein. The hole is a recess falling in the first direction or a through-hole passing through the restraint member in the first direction.

A power storage device includes a case, a power storage element disposed in the case, a lead connected to an electrode of the power storage element, a sealing member sealing an opening of the case. The sealing member includes a gasket and a sealing plate having conductivity. The gasket includes a base having a disk shape. The base is disposed between the sealing plate and the power storage element. The base has a through-hole formed therein. The sealing plate includes a protrusion inserted in the through-hole. The protrusion of the sealing plate is connected to the lead. The protrusion is configured to be displaced in a direction away from the lead in accordance with an increase of an internal pressure of the case so as to be disconnected from the lead.

The invention relates to a composition for forming an adhesive layer, an adhesive layer, a manufacturing method for the adhesive layer, a composite material, a sheet, a heat dissipation member, an electronic device, a battery, a capacitor, an automobile component and a machine mechanism component, and the composition for forming the adhesive layer contains a polyvinyl acetal resin and a compound having an oxazoline group.

The present disclosure generally relates to a venting system that includes a wall of a lid or a container. The lid or container defines a central longitudinal axis, and a line segment that is measured from the longitudinal axis to an outermost surface of the lid or container, and a pressure relief feature that is disposed along the lid or container. The pressure relief feature includes a thinned region of the lid or container that defines a minimum thickness that is less than 40% of a maximum thickness of the respective lid or container.

A heat transfer device includes a bag and a working fluid. The bag includes a first sheet and a second sheet with edges that are sealed together. The working fluid is enclosed in the bag. The working fluid changes a phase thereof between gas and liquid. The bag includes a vaporizing portion in which the liquid-phase working fluid is vaporized and a condensing portion in which the gas-phase working fluid is condensed. The bag includes a two-phase flow channel in which liquid-gas two-phase slug flow including the liquid-phase working fluid and the gas-phase working fluid occurs from the vaporizing portion to the condensing portion. The two-phase flow channel is provided in an internal space of the bag.

A power storage device includes a plurality of power storage modules laminated, a conductive plate and a sealing member. The conductive plate and the sealing member are provided between the power storage modules adjacent to each other in a laminating direction of the power storage modules. The plurality of power storage modules each have an electrode laminate, an electrolytic solution, and a sealing body. The electrode laminate has electrode exposed portions exposed from the sealing body at one end and the other end in the laminating direction. Between the power storage modules adjacent to each other in the laminating direction, the conductive plate is disposed between the electrode exposed portions opposing each other to be in contact with the electrode exposed portions, and at least a portion between the sealing bodies opposing each other is filled with the sealing member.

A energy storage system includes at least one storage cell. The storage cell is provided at least in sections with a casing. The casing consists of plastic and is provided with a material for increasing a thermal conductivity. The material is configured such that a thermal runaway in the event of a fault is reduced.

An energy storage system includes a sealed housing defining an interior space and a plurality of cells arranged within the interior space of the housing. A cooling liquid submerges each of the cells. The cooling system is positioned within the sealed housing configured to actively and passively cool and heat each of the cells.

An energy storage apparatus includes: a plurality of energy storage devices each including a gas release valve, the plurality of energy storage devices being arranged along a predetermined direction in a posture where the gas release valves are directed in the same direction; an exhaust portion disposed on the gas release valves of the plurality of respective energy storage devices, the exhaust portion forming an exhaust path for a gas discharged from the gas release valves; and a housing accommodating the plurality of the energy storage devices and the exhaust portion, wherein the exhaust portion includes an exhaust port portion that protrudes from the housing and forms an outlet portion of the exhaust path.
