Japanese Patent JP5810861
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress a short-circuit failure that occurs between an uncoated part of a foil-shaped positive electrode plate and a foil-shaped negative electrode plate of a battery as much as possible.SOLUTION: In this battery, a power generating element 3 having a foil-shaped positive electrode plate and a foil-shaped negative electrode plate on which an active material layer is formed are laminated with a separator held between them is provided; non-formation portions 3a, 3b where the active material layer is not formed on the foil-shaped positive electrode plate and the foil-shaped negative electrode plate are disposed at the end part of the power generating element 3 in the set direction thereof; and the non-formation portion 3a of the foil-shaped positive electrode plate and the non-formation portion 3b of the foil-shaped negative electrode plate are located on the mutually opposite sides in the set direction, and are disposed while projecting from the separator and the facing foil-shaped negative electrode plate or the foil-shaped positive electrode plate in the set direction. In the separator disposed from a first end part located on the non-formation portion 3a side of the foil-shaped positive electrode to a second end part located on the non-formation portion 3b side of the foil-shaped negative electrode plate, pressing means PS for causing the first end part to be pressed more strongly than the second end part is.
