Abstract: A system configured to suppress thermal runaway in a battery cell. The system includes a battery cell stack including: C cathode electrodes each including a cathode current collector, a cathode active layer arranged on the cathode current collector, and an external connector extending from the cathode current collector; A anode electrodes each including an anode current collector, an anode active layer arranged on the anode current collector, and an external connector extending from the anode current collector; and S separators. C, A, and S are integers greater than one. A chamber is configured to store a suppressant that is configured to suppress thermal runaway. A valve is configured to open in response to a thermal runaway condition at the battery cell stack to release the suppressant from the chamber to the battery cell stack.
