Document Type and Number:
WIPO Patent Application WO/2024/085542
Kind Code:
A1
Abstract:
A method for manufacturing an electrode assembly, according to one embodiment of the present invention, comprises steps in which: a cathode sheet, a separator sheet and an anode sheet are unwound in each of a plurality of roll members; the unwound cathode sheet, separator sheet, and anode sheet form a stack while passing between a pair of guide rolls; and the stack comprising the cathode sheet, the separator sheet, and the anode sheet is punched, wherein, in each of the cathode sheet and the anode sheet, an active material and a non-conductive material are alternately applied on the basis of the driving direction of the guide rolls, and punching of the stack is the punching of a portion to which the non-conductive material is applied.
