    摘要： A short-circuit between a positive electrode and a negative electrode due to a deposit on an electrode plate is prevented in a power storage unit such as a lithium-ion secondary battery. An electrode plate is covered by a folded insulating sheet. Bonding is performed on facing edges of the sheet which overlap with each other in a portion outer than the electrode plate. One or more openings are formed in the electrode plate, and the facing edges of the folded sheet are bonded to each other also in the opening. Such a bonding portion enables the sheet to be in closer contact with the electrode plate and prevents the displacement between the sheet and the electrode plate. When the electrode plate is deformed or vibrated, the sheet can be rubbed against a surface of the electrode plate, thereby removing a deposit from the surface of the electrode plate.

    摘要： A secondary battery with an exterior body having a novel scaling structure, and a structure of a sealing portion that relaxes a stress of deformation are provided. The secondary battery includes a positive electrode, a negative electrode, an electrolyte solution, and an exterior body enclosing at least part of the positive electrode, at least part of the negative electrode, and the electrolyte solution. The exterior body includes a first region having a shape with a curve, a shape with a wavy line, a shape with an arc, or a shape with a plurality of inflection points, and a second region having the same shape as the first region. The first region is in contact with the second region. Alternatively, the first region has a shape without a straight line. The secondary battery may be flexible, and the exterior body in a region having flexibility may include the first region.
