In order to allow a standardized high-capacity cell to selectively have high-output or high-capacity characteristics, a secondary battery includes a can for accommodating an electrode assembly and an electrolyte; a cap assembly mounted on the can; first metal foil attached on a top surface of the cap assembly or a bottom surface of the can; a circuit protection element attached on the first metal foil; and second metal foil attached on the circuit protection clement, wherein a size and a shape of the second metal foil is determined such that a portion of the second metal foil docs not overlap the circuit protection element. |
