Abstract
According to the method for manufacturing electrode sheets, in a first cutting step, an original sheet, including a belt-shaped metal foil and an electrode material coated thereon in a lengthwise direction to form a plurality of coated portions spaced at a predetermined gap, is cut at a location between the coated portions. In a pressing step, the original sheet strips having been cut in the first cutting step are pressed. In this case, the original sheet strips that are pressed by the rolling device are independent from each other. Therefore, the effect produced in rolling of the coated portions remains within each of the original sheet strips. In addition, distortions occurring in the original sheet strips can be prevented from affecting each other and the occurrence of wrinkles can be inhibited.
