Method and apparatus for manufacturing an electrode sheet
Abstract:
A method for manufacturing an electrode sheet including an electrode layer on both surfaces of a current collecting foil includes: feeding out an original electrode sheet including an unfinished electrode layer on each surface of the foil from a feeding part; causing a press roll pair to contact with the original sheet fed out to form the unfinished layers into electrode layers; receiving the sheet having passed through the roll pair by a sheet receiving part; and rotating rolls of the roll pair in a feeding direction. The feeding part, roll pair, and receiving part are placed such that the original sheet and the electrode sheet are to be wound on one of the rolls. The rolls are rotated such that a moving speed of cylindrical surface of one roll placed in a position where the sheets are wound thereon is higher than that of the other roll.
