Abstract:
A pouch cell includes: a storage discharge element having a substantially cuboid shape; a power collection tab lead that is thinner than the storage discharge element and is externally drawn from the storage discharge element; and an exterior film that packages the storage discharge element in a state where the power collection tab lead is externally drawn, wherein the exterior film includes: a holding part that sandwiches the power collection tab lead from front and rear surfaces in a thickness direction; a fold part along an outline of the holding part; and a reinforcement part that is folded from the fold part and is joined to at least the holding part, the fold part is joined to a side portion that extends in a thickness direction of the holding part, the reinforcement part is folded back in a direction of sandwiching the power collection tab lead by the fold part, and the reinforcement part includes an extension portion that extends from the fold part along a drawn direction of the power collection tab lead or a direction that crosses the drawn direction.
Abstract:
What is provided is a solid state battery which can be manufactured with a high yield, has little variation in initial performance, and has a long lifespan and a method of manufacturing the same. A solid state battery includes a flat laminated structure which is obtained by winding an electrode laminated sheet extending from a first end to a second end. In the electrode laminated sheet, a first sheet and a second sheet are disposed while a first connection portion and a second connection portion face each other in a plan view, a first region in which a first solid electrolyte sheet, a first electrode, a second solid electrolyte sheet, and a second electrode piece are laminated in this order and a second region in which a second electrode piece, a first solid electrolyte sheet, a first electrode, and a second solid electrolyte sheet are laminated in this order are alternately formed in a longitudinal direction between the first connection portion and the second connection portion, and the electrode laminated sheet is wound around the first end so that the first electrode and the second electrode piece are alternately laminated so as to overlap each other in a plan view.
Abstract:
The disclosure provides a cell structure of a solid state battery capable of uniformly holding a solid state battery cell in a battery case and a manufacturing method of a solid state battery. In a process of manufacturing a can cell of the solid state battery, a shock absorber is disposed in the battery case after the solid state battery cell is inserted into the battery case and before a can lid is welded. Then, the lid is provided to seal the case. At the time of sealing, the solid state cell and a terminal are fastened by using an engaging member, and the airtightness is improved.
Abstract:
Provided is a battery module having a structure for cooling efficiently without affecting the volume of the entire module. By utilizing dead spaces uniquely present in laminate cells and conducting heat in a lamination direction of electrodes to dissipate the heat, the cooling efficiency is improved without increasing the volume of the entire module.
