Abstract

The present invention provides a method for manufacturing an electrode assembly, comprising: interposing a plurality of first electrodes one by one, which are spaced apart from each other, between two separators; stacking a second electrode on each of outer surfaces of the separators on each of both sides of the first electrode at positions that are skipped by one of the plurality of positions on which the first electrodes are disposed to alternately continuously form a bi-cell, in which the second electrode/the separator/the first electrode/the separator/the second electrode are sequentially stacked, and a half-cell, in which the separator/the first electrode/the separator are sequentially stacked; cutting the stack into a unit cell in which one bi-cell and one half-cell are connected to each other; folding the unit cell so that the bi-cell and the half-cell are stacked; and stacking a plurality of folded unit cells to manufacture the electrode assembly.
