AI Customer ServiceThe LTO battery fire can be quickly extinguished by heptafluoropropane agent, whether it is single battery or multiple ones. The battery fire may be reignited after it is put down because the violent chemical reaction is still ongoing inner the battery and flammable gases eject continuously from the cell.
Therefore, heptafluoropropane is a fire extinguishing agent candidate to put down the lithium titanate battery fire. However, due to the violent reactions still ongoing inner the cell and flammable gases ejecting continuously from the cell, the battery may be reignited after it is put down.
Their results showed that heptafluoropropane is the most effective agent to extinguish the LIB fires compared with CO 2 and superfine dry powder. Liu et al. demonstrated that the dodecafluoro-2-methylpentane-3-one (C 6 F 12 O) exists an optimum dose for suppressing the LIB fires, but its cooling effect is not perfect.
However, Halon agents have severe damage to the ozone layer and are difficult to degrade. As the substitute of Halon, heptafluoropropane fire extinguishing agent (HFC-227ea) is more environmentally friendly, less toxic and shorter lifetime in atmospheric, and most importantly, it is electrically insulating.
Physical cooling and blocking the chemical reaction of combustion are the main principles for HFC-227ea to extinguish battery fire. The fire was put down within a very short period of time in all the four tests, which indicates that the HFC-227ea can be used to suppress the LTO battery fires.
Rao et al. conducted several fire extinguishing tests using lithium iron phosphate batteries. Their results showed that heptafluoropropane is the most effective agent to extinguish the LIB fires compared with CO 2 and superfine dry powder.
