Original Abstract Submitted

An apparatus for a battery cell is provided. The apparatus includes the battery cell. The battery cell includes an electrode stack including at least one pair of an anode electrode and a cathode electrode and a can including a wall encapsulating the electrode stack. The battery cell further includes a positive battery terminal connected to the electrode stack and projecting outside of the can. The battery cell further includes a negative battery terminal connected to the electrode stack. The positive battery terminal and the negative battery terminal are configured for providing electrical energy. The battery cell further includes a thermal barrier adjoining the can and the positive battery terminal. The thermal barrier seals gases within the battery cell from exiting the battery cell between the can and the positive battery terminal at an ambient temperature of at least 600° C.
