SEPARATOR-INTEGRATED ELECTRODE, BATTERY, AND BATTERY MANUFACTURING METHOD

摘要

A separator-integrated electrode has: an electrode (160) consisting of a negative electrode or a positive electrode; and two separators (170) disposed by sandwiching the electrode (160) therebetween and joined through first heat welding portions (180, 181) and a second heat welding portion (182). The electrode (160) has one side (161) on which a collector foil (162) for taking generated electricity to the outside is disposed. The collector foil (162) has a pair of side portions (162A) projecting from the one side (161). The first heat welding portions (180, 181) are disposed overlapping with the pair of side portions (162A) in a plan view. The second heat welding portion (182) is disposed outside the other side (163) disposed on the opposite side of the one side (161). The present invention can sufficiently prevent the position shift between an electrode and a separator from occurring when stacking and assembling are performed.
