Abstract
A secondary battery includes an electrode assembly, a can housing the electrode assembly, the can having a long axis and a short axis, and a cap plate that seals an opening of the can. The can includes a first side surface and a second side surface that face each other so as to correspond to the short axis of the can, the first side surface and the second side surface having a first thickness, a third side surface and a fourth side surface that face each other so as to correspond to the long axis of the can, the third side surface and the fourth side surface having a second thickness, the second thickness being greater than the first thickness, and a bottom surface that is located opposite the opening of the can and contacts the first through fourth side surfaces, the bottom surface having a third thickness.
