Method for Manufacturing Electrode Assembly and Electrode Assembly

A method for manufacturing an electrode assembly includes preparing a cell stack and forming a bonding part. In the preparing, a first electrode and a second electrode having a width greater than that of the first electrode are alternately stacked with a separator therebetween. In the forming, a bonding part is folded toward the cell stack by bonding the plurality of separators protruding outward further than the first electrode and the second electrode to each other. An electrode assembly is also provided.
