Abstract:

The demand for lightweight battery enclosures in new energy vehicles has led to the increased use of aluminum alloys and polymer composites. However, the potential hazards associated with thermal runaway events in high-energy-density batteries necessitate advanced fire mitigation strategies. This study introduces a ceramic-enhanced fire-protection coating designed to prevent catastrophic thermal failures in battery enclosures. Torch and grit testing (TaG) was performed according to UL 2596 battery enclosure material testing standard, and the fire resistance of the battery enclosures was significantly improved after applying the coating.
