Liu et al. reported that when the surface temperature of a lithium iron phosphate (LiFePO 4) battery exceeds 150 ℃, there is a high risk of TR along with the release of a large amount of combustible gas. The gas burns when exposed to an open flame, leading to a more severe TR of the battery at high ambient temperatures .
The fire extinguishing effect of dry powder on lithium iron phosphate battery was analyzed. The fire hazard resulting from the thermal runaway (TR) of lithium-ion batteries (LIBs) poses a great threat, but it is still a challenge to extinguish LIB fires effectively and promptly.
