The first electrode tab includes a joining portion joined to the uncoated portion and an extension portion extended outward from the joining apportion. A width of the joining portion is wider than a width of the extension portion. The joining portion is wound ¾ times or more and once or less in the central portion of the jelly-roll electrode assembly.",
