Beschreibung
Zusammenfassung:	An electrode assembly and rechargeable battery, the electrode assembly including a first electrode including a first sub-electrode in which an active material is on both surfaces of a base substrate, a second sub-electrode in which the active material is on one surface of the base substrate, and a first electrode uncoated region extending from the first sub-electrode; a second electrode including a third sub-electrode in which an active material is on both surfaces of a base substrate, a fourth sub-electrode in which the active material is on one surface of the base substrate, and a second electrode uncoated region extending from the third sub-electrode; and a separator between the electrodes, wherein the active material at the third sub-electrode includes a protruding portion protruding therefrom, and a distance from the end of the active material at sides based on the third sub-electrode to the protruding portion is 0 to 3 mm.
