  • Patent number: 11211597
    Abstract: A method for manufacturing an electrode belt that includes pressing a belt-shaped current collector foil with an electrode mixture layer along a longitudinal direction in a thickness direction of the electrode mixture layer so that the electrode mixture layer is formed on a part of the current collector foil, and stretching, by a stretching roll, a non-forming part of the current collector foil in which the electrode mixture layer is not formed and in which the current collector foil is exposed in respective ends in a width direction. The stretching roll includes a first roll opposed to the electrode mixture layer, and a pair of second rolls arranged in respective ends of the first roll in an axial direction and opposed to the non-forming part. A central axis of the first roll is deviated with respect to a central axis of the pair of second rolls.
