Abstract
A method for manufacturing an electrode according to the present disclosure includes an electrode film manufacturing step of manufacturing a sheet-like electrode film by passing a powder-type mixture between sheeting rollers and supplying the electrode film at a predetermined speed; an electrode manufacturing step of additionally feeding an electrode foil, and manufacturing an electrode by passing between the rolling rollers in a state where the electrode film and the electrode foil are laminated and bonding them to each other; a rolling roller control step of sensing the thickness of the electrode before the electrode is recovered and controlling the gap size between the rolling rollers and the rotational speed of the rolling rollers; and a feedback control step of feedback controlling the electrode film manufacturing step so that the thickness and supply speed of the electrode film are adjusted in accordance with the gap size between the rolling rollers or the rotational speed of the rolling rollers. The manufacturing method according to the present disclosure may suppress the occurrence of wrinkles in the electrode.
