The an electrode assembly includes a plurality of negative electrodes each including a negative electrode tab and a plurality of positive electrodes arranged alternately with the negative electrodes and each including a positive electrode tab, a first current collector electrically connected to the negative electrodes, and a first insulator disposed below the first current collector, wherein negative electrode tabs of at least some of the plurality of negative electrodes overlap in a first position to form a first negative electrode tab stack and negative electrode tabs of the others of the plurality of negative electrodes overlap in a second position, different from the first position, to form a second negative electrode tab stack, and the first insulator is disposed adjacent to the first negative electrode tab stack and the second negative electrode tab stack simultaneously.",
