Patent attributes
A sealed battery of the present invention includes a power generation element including an electrode sheet and a separator; a laminate film disposed in such a way as to enclose the power generation element therein; an electrode connection terminal connected to the electrode sheet; and an electrolyte. The laminate film is shaped to form a housing section for power generation element, the housing section being hermetically sealed at a fusion bonding section where parts of the laminate film are overlapped and fusion-bonded and at a first sealing section where the electrode connection terminal is sandwiched between and fusion-bonded with parts of the laminate film. The power generation element and the electrolyte are housed in the housing section for power generation element. The electrode connection terminal comprises an external connection section for connecting with external and a conductive section disposed between the external connection section and the first sealing section. The conductive section is covered with the laminate film without bonding.
