Abstract
A device for winding an electrode plate includes a feed roller configured to guide a first electrode plate or a second electrode plate, each of the first electrode plate and the second electrode plate including a plurality of electrode tabs protruding from one side, a deformation reducing member spaced apart from an outer circumferential surface of one end of the feed roller and configured to guide the electrode tabs fed to the feed roller to be brought into close contact with the outer circumferential surface of the one end of the feed roller to reduce deformation of the electrode tabs, and a winding unit configured to wind together the first electrode plate or the second electrode plate transferred by the feed roller and a separator interposed between the first electrode plate and the second electrode plate.
