Abstract
The present invention relates to a method for manufacturing a secondary battery. The method comprises: a first process (S) of manufacturing an incomplete electrode assembly; a second process (S) of preparing a pattern member on which a patterned pressing protrusion is formed; a third process (S) of stacking the pattern member on an outer surface of the incomplete electrode assembly; a fourth process (S) of partially pressing the incomplete electrode assembly to pattern-bond an interface between the electrode and the separator and thereby to manufacture a complete electrode assembly; a fifth process (S) of accommodating the complete electrode assembly into a case; a sixth process (S) of injecting an electrolyte to impregnate the electrolyte into the electrode assembly; a seventh process (S) of sealing an unsealed surface to manufacture a secondary battery; and an eighth process (S) of heating and pressing an entire surface of the secondary battery.
