A secondary battery including an electrode assembly. The electrode assembly includes a first electrode including a plurality of first electrode tabs extending to a side of the first electrode, a second electrode including a plurality of second electrode tabs extending to a side of the second electrode, and a separator between the first electrode and the second electrode and insulating the first electrode and the second electrode from one another. The electrode assembly is in a wound jelly roll shape. The plurality of first electrode tabs are in one of four quadrants formed by a long axis and a short axis of the wound electrode assembly. The plurality of second electrode tabs are in a different one of the four quadrants.
