摘要:
Four sides of a rectangular bag-like separator 10 are composed of two adjacent separator thermo-bonding sides 10a and 10c where thermo-bonding portions are formed and of two adjacent insertion opening sides 10b and 10d forming one insertion opening 11 into which an electrode 30 can be inserted. A thermo-bonding section is formed in a portion of at least one of the insertion opening sides 10b and 10d.
摘要:
A film-covered electric device has an electric device element and casing films. The casing films include a sealing area formed by thermally fusing the facing surfaces of the casing films together around the periphery of the electric device element, an electric device element receiving part encapsulating the electric device element inside the sealing area, and unfused portions formed in the shape of cove communicating with the electric device element receiving part. The casing films further include a stress concentrating portion touching the unfused portions for concentrating thereon the peeling stress of the casing films generated at the sealing area by the expansion of the electric device element receiving part, and a pressure releasing part is formed in the stress concentrating portion.
