Among the diverse battery landscape, Lithium Iron Phosphate (LiFePO4) batteries have earned a reputation for safety and stability. But even with their stellar track record, the question of potential fire hazards still demands exploration.
For lithium iron phosphate (LFP) batteries, it is necessary to use an external ignition device for triggering the battery fire. Liu et al. have conducted TR experiments on a square NCM 811 battery at 100 % charge state. The violent combustion was observed for battery.
This research examined the flame retardant (FR) FPPN in 5 Ah lithium-ion battery (LIB) cells under large-scale conditions to assess its resilience under abusive scenarios such as nail penetration, external short-circuiting, overcharging, and thermal stress.
At present, the common flame retardants for batteries are mainly fluorine- and phosphorus-containing substances. Such flame retardants may have an impact on the environment during the preparation and processing.
In extreme situations like the recent LA wildfires, there's not much that can stop batteries from burning along with everything else in the fire's paths. Removing excess fire retardants won't stop that, the researchers say, but at least they won't make an already dangerous situation worse.
