Abstract
Disclosed are an electrode assembly and a method for manufacturing the electrode assembly.According to the present invention, the electrode assembly may be manufactured in consideration of deformation of the electrode assembly and a secondary battery due to a swelling phenomenon to improve assemblability and storage ability of the secondary battery having a curved surface with respect to electronic devices.According to an aspect of the present invention for achieving the above effects, provided is an electrode assembly having a curved surface, wherein a curvature radius (Re) of each of ends of the curved surface is less than a curvature radius (Rc) of a central portion of the curved surface.
