Abstract: A method of manufacturing a laminate-type battery is disclosed. The battery includes an electrode body, a side member disposed at a side face of the electrode body, and a laminate film covering the electrode body and a part of the side member, the side member being disposed at a position that is offset to a first side in a longitudinal direction of the side face relative to a center of the side face in the longitudinal direction. The method includes welding the laminate film so as to cover the electrode body and a part of the side member. The side member is shaped such that a thickness of the side member in a transverse direction of the side face increases continuously towards the first side.

Abstract: A method of fabricating an electrode includes: fabricating a first electrode layer disposed on a current collector; and fabricating a second electrode layer disposed on the first electrode layer. The first electrode layer is formed by electrostatic deposition, wet deposition, or rolled film formation. The second electrode layer is formed by rolled film formation. When the first electrode layer is fabricated by rolled film formation, at least part of a surface of active material particles used in the rolled film formation is coated with a resin that is different from polytetrafluoroethylene.

Abstract: A cutting device includes: a conveyance unit that conveys a continuous body of a plurality of electrode plates; a laser scanning unit that scans the continuous body with laser light; and a control unit that controls the laser scanning unit. The control unit controls a laser scanning unit so as to scan the continuous body while performing intermit irradiation with laser light, thereby forming a plurality of unit cutting sections that are continuous and dividing the continuous body into a first portion and a second portion. The unit cutting sections have a main line section extending along the boundary of the first portion and the second portion, and a bent section that bends and extends from an end of the main line section.

Abstract: A laminated battery includes an electrode stack including a plurality of electrodes stacked together and having a cuboid shape, and a laminate film covering and sealing the electrodes. The laminate film includes a film body covering four surfaces of the electrode stack, a film partitioning wall interposed between two adjacent electrodes of the plurality of electrodes, and cover members that are twice as many as the electrodes. The film body and the film partitioning wall define accommodating portions respectively accommodating the electrodes. The cover members cover two remaining uncovered sides of each accommodating portion. The cover members each have a recess-shaped portion including a bottom wall and four side walls. An outer surface or an inner surface of the bottom wall faces a side surface of a corresponding one of the electrodes. Outer surfaces of the side walls are fusion-bonded to the film body or the film partitioning wall.
