Abstract
A secondary battery including: an electrode assembly; a case receiving the electrode assembly and including a plurality of stepped sections at an inner side of the case in contact with the electrode assembly; and at least one electrode tab electrically connected with the electrode assembly and withdrawn toward an outside of the case. In the secondary battery, a friction force between the inner side of the case and the electrode assembly is increased due to the plurality of stepped sections, thereby minimizing or reducing movement of the electrode assembly within the case.
