Document Type and Number:

WIPO Patent Application WO/2021/118033

Kind Code:

A1

Abstract:

The present invention relates to an electrode assembly manufacturing method, which comprises: (a) a step for transferring, to a first position, an electrode assembly which comprises multiple electrodes and multiple separators that are alternately stacked; (b) a step for forming adhesive layers on both transverse side portions of the separators included in the electrode assembly in the first position; (c) a step for moving a pair of pressing blocks provided in a second position in directions such that same correspond to each other, the interval between the pair of pressing blocks being formed to be smaller than the transverse length of the separators and larger than the transverse length of the electrodes; (d) a step in which, when the electrode assembly in the first position is moved down so as to be inserted between the pair of pressing blocks provided in the second position, the opposite side portions of the separators are bent upward by being brought into contact with the pressing blocks; and (e) a step in which, when the pair of pressing blocks are moved toward the electrode assembly, the bent opposite side portions of the separators overlap each other and are bonded to each other by the adhesive layers.
