Patent number: 10923698Abstract: A laminate-type power storage element includes a flat plate-shaped electrode body and an exterior body. The electrode body is configured by stacking a sheet-shaped positive electrode and a sheet-shaped negative electrode on either side of a separator. The exterior body is formed in a flattened bag-shape by thermocompression bonding peripheral edge regions of two opposing laminated films, to seal the electrode body inside the flattened bag-shape of the exterior body together with an electrolyte. The separator has a sheet-shaped substrate and at least one bonding layer formed on at least one surface of the substrate. A peripheral edge portion of the separator is sandwiched between and bonded by the two laminated films at a peripheral inside of the peripheral edge regions of the two laminated films.Type: GrantFiled: May 17, 2018Date of Patent: February 16, 2021Assignee: FDK CORPORATIONInventors: Yuya Iida, Yasuaki Egawa, Daisuke Hirata, Ryuji Ito, Akihiro Yamamoto
