A device for aiding in the fracture of a vent of an electrochemical cell includes a main body having a first surface and a plurality of lobes extending out from the first surface of the main body such that an open space is provided between adjacent lobes. Each of the plurality of lobes are configured to make contact with the vent during deployment of the vent such that the vent completely separates from a bottom of the electrochemical cell. The open space provided between adjacent lobes is configured to allow gases from inside the electrochemical cell to pass through during deployment of the vent.
