METHOD FOR MANUFACTURING STACKED METAL FOIL, METHOD FOR MANUFACTURING SEALED CELL INCLUDING SAID METHOD, AND SEALED CELL |
摘要 |
The method for manufacturing a laminated metal foil (1) according to the present invention includes: a first step of forming, in a weld site (A) of laminated layers of a metal foil (2), by the use of a cutter (C) whose longitudinal cross-sectional shape is a substantially V-shape, a notch (3) that is linear in a planar view and penetrates the laminated layers of the metal foil (2) in a lamination direction (S), to cause the laminated layers of the metal foil (2) to bond to each other along the lamination direction (S) at ends (3a) of a linear notch; and a second step of bringing an electrode (E) for resistance welding into press-contact with the weld site (A) and then energizing the weld site (A) via the electrode (E), to perform resistance welding on the laminated metal foil (1). |
