Method and apparatus for manufacturing an electrode sheet

A method for manufacturing an electrode sheet, the electrode sheet including an electrode layer on both surfaces of a current collecting foil, the method comprising the steps of:

• feeding out an original electrode sheet from an original sheet feeding part, the original electrode sheet including an unfinished electrode layer on each of the surfaces of the current collecting foil;
• causing a press roll pair including a pair of rolls to contact with the original electrode sheet from both sides, the original electrode sheet being fed out from the original sheet feeding part, to form the unfinished electrode layers into electrode layers;
• receiving the electrode sheet having passed through the press roll pair by an electrode sheet receiving part;
• and
• causing a driving part to rotate each of the rolls of the press roll pair in a feeding direction of the original electrode sheet and the electrode sheet,
• wherein the original sheet feeding part, the press roll pair, and the electrode sheet receiving part are placed in a positional relationship such that the original electrode sheet and the electrode sheet are to be wound on one of the rolls of the press roll pair, and
• the rolls of the press roll pair are driven by the driving part to rotate such that a moving speed of cylindrical surface of an inner roll corresponding to one of the rolls, the inner roll being placed in a position where the original electrode sheet and the electrode sheet are wound on the inner roll, is higher than a moving speed of cylindrical surface of an outer roll corresponding to the other roll.
