Abstract
Provided is a secondary battery including an electrode assembly, a case accommodating the electrode assembly, and a cap assembly, including a cap plate having a short-circuit hole, configured to seal the case. The secondary battery includes a first connection plate at an exterior surface of the case and coupled to the electrode assembly, a capacitive member between the first connection plate and the cap plate, and a short-circuit unit including an inversion plate positioned in the short-circuit hole, and a second connection plate at an exterior side surface of the case spaced apart from the cap plate and extending over at least a portion of the short-circuit hole, the second connection plate being coupled to the electrode assembly.
