The present invention relates to a method for manufacturing a secondary battery. More particularly, the present invention relates to a method for manufacturing an electrode assembly by laminating multiple bi-cell type and/or mono-cell type unit cells. The electrode assembly manufacturing method according to the present invention is advantageous in that curvatures, which have occurred in the unit cells due to a roll lamination process, are easily removed, and a planar-shaped electrode assembly can be manufactured through a simple process. There is another advantage in that, when an electrode assembly is manufactured by the above method, curvatures between unit cells, which constitute the electrode assembly, counterbalance each other, thereby remarkably lengthening the period of time during which the electrode assembly maintains the planar shape. |
