Fire Protection Engineers Address Li-ion Safety >> Evaluation Engineering


“… it’s possible that if you have a battery failure and there is a bunch of batteries in close proximity, the failure of one could lead to a failure of adjacent batteries.” Such scenarios, he said, are what fire-protection engineers are looking at now.

(battery) failures, Long, Kahn, and Mikolajczak wrote, can result in increases of cell temperature and pressure. Subsequently, the cell may undergo venting, vent gasses may ignite, contents may be ejected, and thermal runaway may propagate to adjacent cells.

“Halon 1301, the fire extinguishing agent in passenger aircraft cargo compartment fire suppression systems, has no observable effect on a metal battery fire.”

the proliferation of electric vehicles, with charging stations in public areas and in residences, further noting that batteries may be stored at battery-switching locations, thereby posing “high-voltage and fire safety challenges in addition to those associated with Li-ion batteries themselves.”
