SYSTEMS FOR SUPPRESSING THERMAL RUNAWAY IN BATTERY CELLS
This abstract first appeared for US patent application 20250149683 titled 'SYSTEMS FOR SUPPRESSING THERMAL RUNAWAY IN BATTERY CELLS
Original Abstract Submitted
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.
