Abstract: A battery cell for a vehicle includes a cell can having a first wall, a second wall, a first side wall and a second side wall. The first wall, the second wall, the first side wall, and the second side wall defining an electrode stack receiving zone. A vent is formed in the second wall. The vent is spaced from the first side wall and the second side wall. The vent fluidically connects the electrode stack receiving zone with an exterior of the cell can. An electrode stack is positioned in the electrode stack receiving zone. The electrode stack is spaced from of the first side wall by a channel. A cell stack support is arranged in the electrode stack receiving zone and supporting the electrode stack above the second wall. The cell stack support includes at least one passage that transports gases from the channel to the vent.

Abstract: 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.
