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 partially pressing the incomplete electrode assembly to manufacture a complete electrode assembly in which a bonding portion and a nonbonding portion coexist; a third process (S) of accommodating the complete electrode assembly into a case; a fourth process (S) of injecting an electrolyte through an opening of the case to impregnate the electrolyte into the electrode assembly; a fifth process (S) of sealing an unsealed surface in which the opening of the case is formed to manufacture a secondary battery; and a sixth process (S) of heating and pressing an entire surface of the secondary battery to bond the nonbonding portion of the interface between the electrode and the separator.
