Beschreibung
Zusammenfassung:	A rechargeable battery includes an electrode assembly having a first electrode, a separator, and a second electrode; a case accommodating the electrode assembly; an electrode terminal; a first current collecting plate connecting the first electrode to the electrode terminal; a vent plate; a second current collecting plate connecting the second electrode to a beading portion of the case at an inner side of the vent plate; and a gasket between the second collecting plate and the vent plate and between the second collecting plate. The second current collecting plate includes a base portion on the second electrode, a bottom welding portion extending in a radial direction from the base portion and welded to the second electrode, and a wing welding portion spaced apart from the bottom welding portion and connected to the base portion by an elastic portion and welded to the beading portion.
