Abstract
The present invention relates to an electrode assembly including a multi-tab in which tabs are capable of being aligned and a method for manufacturing the same. The method for manufacturing an electrode assembly according to the present invention includes a stacking step of repeatedly stacking a negative electrode, a separator, and a positive electrode so that the separator is stacked between the negative electrode including an electrode tab and the positive electrode including an electrode tab to form an electrode stack, an electrode tab coupling step of coupling the electrode tabs having at least two or more same polarities of the electrode tabs of the electrode stack to each other, and a winding step of winding the electrode stack.
