  • Patent number: 10811694
    Abstract: 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.

  • Patent number: 10219395
    Abstract: To provide a power storage unit having a structure which is unlikely to break down by change in shape, such as bending. An electrode plate is covered with a sheet of an insulator which is folded in two. The sheet is preferably processed into a bag-like shape or an envelope-like shape by bonding overlapping portions of the sheet in the periphery of the electrode plate. The electrode plate and the sheet are fixed to an exterior body. In the case where the shape of the exterior body is changed by bending or the like, the electrode plate and the sheet can slide together in the exterior body. Thus, stress on the electrode plate due to bending can be relieved.
