Abstract: An explosion-proof device for a battery comprises: a vent formed in a battery shell of the battery; a valve core movably disposed in the vent to seal and open the vent; a support mounted on an outer wall of the battery shell; and an elastic element. One end of the elastic element is connected to the support and another end of the elastic element is connected to the valve core so as to normally push the valve core to seal the vent. Each of a power battery and a power battery module includes the explosion-proof device.
