Abstract

A method for manufacturing an electrode assembly according to the present invention comprises: a step (a) of transferring an electrode, in which a plurality of electrodes and a plurality of separators are alternately stacked, to a first position; a step (b) of forming an adhesive layer on both side portions of the separators, which are provided in the electrode assembly disposed at the first position, in a full width direction; a step of (c) of allowing the pair of pressing blocks provided at a second position to move in a direction corresponding to each other, wherein an interval between the pair of pressing blocks is less than a length of each of the separators in a full width direction and is greater than a length of each of the electrodes in a full width direction; a step (d) of allowing both the side portions of the separator to be bent upward while being in contact with the pressing blocks when the electrode assembly disposed at the first position descends to be inserted between the pair of pressing blocks provided at the second position; and a step (e) of allowing both the bent side portions of the separator to be adhered each other by an adhesive layer while overlapping each other when the pair of pressing blocks moves toward the electrode assembly.
