Secondary battery and method of manufacture

A secondary battery and a method of manufacturing the secondary battery. A secondary battery includes an electrode assembly formed through winding a positive electrode plate including a positive electrode uncoated portion, a negative electrode plate including a negative electrode uncoated portion, and a separator between the positive and negative electrode plates. A part of the positive electrode uncoated portion and a part of the negative electrode uncoated portion are removed to form a positive electrode tab and a negative electrode tab at first and second ends, respectively, of the electrode assembly.
