Abstract: A rechargeable battery includes an electrode assembly including spiral-wound a first electrode, a first separator, second electrode, and a second separator, the first electrode, first separator, second electrode, and second separator being sequentially disposed around a center, a case receiving the electrode assembly, and a cap assembly coupled to an opening of the case, wherein the first separator and the second separator enclose first ends of the first electrode and the second electrode at the center, portions of the first and second separators defining a re-spiral-wound region having at least a first portion disposed between the first electrode and the second electrode in a diameter direction of the electrode assembly.
