DEVICES, SYSTEMS, AND METHODS FOR CONTROLLING VENT GASES AND EJECTA FROM THERMAL RUNAWAY EVENTS IN ENERGY STORAGE SYSTEMS

The present disclosure relates to materials and systems to manage thermal runaway issues in battery modules. In exemplary embodiments, a battery module includes battery cells separated by spacer elements. To mitigate thermal runaway issues, spacer elements may be extended to the interior surface of the enclosure. A seal is formed between the spacer elements and the interior wall to form a thermal barrier between adjacent battery cells.
