  "textContent": "An embodiment of the present disclosure provides a rechargeable battery that may prevent interference between a current collecting plate and an electrode uncoated portion while securing sealing force of a case opening by a gasket. An embodiment provides a rechargeable battery including: an electrode assembly formed by winding a first electrode, a separator, and a second electrode; a case accommodating the electrode assembly; an electrode terminal installed in an insulating state at a first opening on one side of the case; a first current collecting plate that connects the first electrode to the electrode terminal; a vent plate sealing a second opening on the other side of the case; 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 interposed between the second collecting plate and the vent plate and between the second collecting plate and the case to perform a sealing action by a crimping portion connected to the beading portion, wherein the second current collecting plate includes a base portion disposed on an uncoated portion of the second electrode, a bottom welding portion extending in a radial direction from the base portion and welded to the uncoated portion of the second electrode, and a wing welding portion spaced apart from the bottom welding portion to be connected to the base portion by an elastic portion and welded to the beading portion.",
