摘要: A film structure for a battery for dispensing on a round body includes a carrier film having a first section and a subsequent second section and a first electrode layer for forming an anode or a cathode, and a second electrode layer for forming an anode, if the first electrode layer is formed as a cathode, or a cathode, if the first electrode layer is formed as an anode. The first and second electrode layers are arranged on a top side of the first section and the second section of the carrier film. While the underside of the second section of the carrier film is coated with an adhesive layer, the underside of the first section of the carrier film is free of adhesive. As a result, the first section of the carrier film can be folded over onto the second section of the carrier film during labeling and the battery can be thereby activated.

摘要: A method for producing an electrode assembly includes a step of ultrasonically welding an exposed portion where the surface of an electrode current collector is exposed and an electrode lead to each other. The ultrasonic welding is performed, while the exposed portion of the electrode current collector and the electrode lead are stacked on each other, with an ultrasonic horn pressed against a resin sheet disposed on the exposed portion or the electrode lead. The resin sheet includes a sheet base material and an adhesive layer formed on one surface of the base material and is bonded to a portion of the exposed portion that is to be in contact with the ultrasonic horn or to a portion of the electrode lead that is to be in contact with the ultrasonic horn.
