Abstract: A battery with passive fire suppression capabilities includes a housing, a battery cell stack disposed within an interior of the housing, and a fire suppression material disposed within the interior of the housing. The battery cell stack includes a plurality of battery cells, with each of the plurality of battery cells including a nonaqueous electrolyte. When the fire suppression material is exposed to the nonaqueous electrolyte, the fire suppression material is configured to retain the nonaqueous electrolyte within the interior of the housing.

Abstract: A battery system includes a battery housing having an interior compartment. A battery pack, including a plurality of battery cells, is in the interior compartment of the housing. A vessel defines an interior chamber and includes an air inlet, an oxygen discharge port, and an inert gas discharge port each in communication with the interior chamber. An oxygen separation material is in the chamber and is configured to separate oxygen from air supplied through the air inlet and to direct the oxygen to the oxygen discharge port. The oxygen separation material is further configured to direct remaining oxygen deficient air to the inert gas discharge port. The inert gas discharge port in communication with the interior compartment of the battery housing.
