Cylindrical Secondary Battery, Battery Pack, And Movement Means

Abstract: The present specification provides a cylindrical secondary battery, a battery pack, and a movement means, the cylindrical secondary battery having a structure in which a first electrode, a second electrode, and a separator interposed therebetween are sequentially stacked and wound, wherein the first electrode includes an uncoated portion on which an active material is not coated on one surface of a current collector. The uncoated portion comprises: an electrode assembly including a first electrode tab bent from an end of the electrode assembly in a winding center or outward direction; a battery can for accommodating the electrode assembly through an opening formed on one side thereof; a current collecting plate including three or more tab coupling portions electrically connected to the first electrode tab, and can coupling portions having a continuous outer circumferential surface extending from ends of the tab coupling portions toward the opening of the battery can and electrically connected to the inner surface of the battery can; and a top cap for covering the opening of the battery can.
