Abstract
A method is performed to produce a film-covered battery in which electrode tabs extend out from joining surfaces on a first side of lamination films, in which a seal line is formed along the first side and traversing the electrode tabs. Pressure and/or heat is applied only to tab regions of the seal line using tab-region heat blocks, and then pressure and/or heat is applied only to non-tab regions using non-tab-region heat blocks.
