Abstract

The present application provides a rechargeable battery including a battery case and a battery cap coupled to the battery case. The battery cap includes a conductive cap plate; a first electrode electrically connected to the cap plate; a second electrode insulatively connected to the cap plate, the second electrode being in electrical connection with one end of a conductive plate for securing the second electrode to the conductive cap plate; and a conductive turnover component in electrical connection with the conductive cap plate, the turnover component being initially separated from the conductive plate and capable deforming to contact other end of the conductive plate due to high pressure in the battery case, so as to short-circuit the first electrode and the second electrode.
