  • Publication number: 20230335835
    Abstract: This exterior material for a power storage device is constituted of at least an outside layer, a barrier layer, and an inside layer, in that order from the outer side. The inside layer includes a compound represented by general formula (A). (In general formula (A), R11 and R12 each independently represent an alkyl group having 1 to 18 carbons, or a phenyl group that optionally has a substituent.

  • Publication number: 20230198059
    Abstract: A outer package material for all-solid-state batteries, said outer package material being composed of a multilayer body that is sequentially provided, from the outer side, with at least a base material layer, a barrier layer and a thermally fusible resin layer in this order, while exhibiting excellent insulating performance in a high temperature environment and excellent followability to the expansion and contraction of a solid electrolyte during charging and discharging of an all-solid-state battery. An outer package material for all-solid-state batteries, said outer package material being composed of a multilayer body that is sequentially provided, from the outer side, with at least a base material layer, a barrier layer and a thermally fusible resin layer in this order, wherein the thermally fusible resin layer is formed of a polybutylene terephthalate film that contains an elastomer.

  • Patent number: 9437881
    Abstract: There is provided a reinforcing material equipped with a cohesive/adhesive layer, having a proper initial adhesion force to an adherend, such as an electrolyte membrane, a catalyst layer and a gas diffusion layer, and which can be temporarily fixed readily. A reinforcing material produced by forming a cohesive/adhesive layer on a substrate. The cohesive/adhesive layer includes an aliphatic polyamide, an epoxy resin and a polythiol. When the reinforcing material is used, it becomes possible to correct the position of an adherend after the adhesion of the reinforcing material to the adherend. In addition, it can prevent the formation of wrinkles on the adherend or the like upon the adhesion of the reinforcing material. Therefore, a catalyst layer laminated membrane or the like which has a reinforcing material attached thereto can be produced readily without requiring the employment of any highly skilled technique.
