Patent number: 11731398Abstract: Provided is a packaging material for a power storage device capable of securing excellent formability without causing pinholes and/or cracks even when deep depth forming is performed and also capable of sufficiently preventing delamination even when deep depth forming is performed or even when it is used under severe environments, such as, e.g., high temperature and high humidity. [Solving means] The packaging material for a power storage device has a configuration including a heat resistant resin layer 2 serving as an outer layer, a heat fusible resin layer 3 serving as an inner layer, and a metal foil layer 4 disposed between both the two layers. The heat resistant resin layer 2 is composed of a heat resistant resin film with a hot water shrinkage percentage of 1.5% to 12%. The heat resistant resin layer 2 and the metal foil layer 4 are bonded via an outer adhesive layer 5 composed of a cured film of an electron beam curable resin composition.Type: GrantFiled: April 28, 2017Date of Patent: August 22, 2023Assignee: Showa Denko Packaing Co., Ltd.Inventors: Wei He, Terutoshi Kumaki, Makoto Karatsu, Takashi Nagaoka

Publication number: 20230243606Abstract: A heat exchanger includes an outer packaging member. The outer packaging member is configured to allow a heat transfer medium flowed to an inside of the outer packaging member from a heat transfer medium inlet to pass through the inside and flow out from a heat transfer medium outlet. The outer packaging member is made of outer packaging laminate materials each including a metal heat transfer layer and a resin thermal fusion layer provided on one surface of the heat transfer layer. The outer packaging laminate materials are superimposed one on the other. The thermal fusion layers are integrally bonded along peripheral edge portions of the outer packaging laminate materials. The heat transfer layer and the thermal fusion layer of the outer packaging laminate material are laminated via an inner adhesive agent layer made of an acid-modified polyolefin-based adhesive agent containing an acid-modified polyolefin-based resin.Type: ApplicationFiled: March 29, 2021Publication date: August 3, 2023Applicant: SHOWA DENKO PACKAGING CO., LTD.Inventors: Koji MINAMITANI, Terutoshi KUMAKI

Publication number: 20190344541Abstract: A packaging material shortens the lead time, improves productivity, and also secures excellent formability. The packaging material includes a base layer as an outer layer, a heat fusible resin layer as an inner layer, and a metal foil layer arranged between both the layers. The base layer and the metal foil layer are bonded via an outer adhesive layer composed of a cured film of a first electron beam curable resin composition containing an electron beam polymerization initiator. The heat fusible resin layer and the metal foil layer are bonded via an inner adhesive layer composed of a cured film of a second electron beam curable resin composition containing an electron beam polymerization initiator. The content rate of the electron beam polymerization initiator in each of the first electron beam curable resin composition and the second electron beam curable resin composition is 0.1 mass % to 10 mass %.Type: ApplicationFiled: July 3, 2017Publication date: November 14, 2019Applicant: SHOWA DENKO PACKAGING CO., LTD.Inventors: Wei HE, Terutoshi KUMAKI, Takashi NAGAOKA, Makoto KARATSU

Publication number: 20110189476Abstract: The present invention relates to a method for producing an organized clay composite, wherein a step for cation exchanging an interlayer metal cation of a lamellar clay mineral to an organic onium ion by swelling the lamellar clay mineral with water or an aqueous solvent and then adding and mixing thereinto an emulsion which is obtained in advance by emulsifying a curable resin composition with use of an organic onium salt or with use of an organic onium salt and a nonionic surfactant, and a step for introducing the curable resin composition into the interlayer of the lamellar clay mineral are performed simultaneously. The present invention also relates to an organized clay composite obtained by the method. The present invention further relates to a resin molded product obtained by molding/curing such an organized clay composite.Type: ApplicationFiled: August 5, 2008Publication date: August 4, 2011Applicant: SHOWA DENKO K.K.Inventor: Terutoshi Kumaki
