Lithium Fire Extinguishers
A malfunctioning Li-ion battery can spontaneously ignite and trigger a chain reaction called “thermal runaway”. Heat travels rapidly through all the battery’s cells, sparking multiple fires that can spread quickly to nearby materials.
The battery creates its own flammable gases and heat, and it won’t stop burning until every cell has discharged all its energy. The only type of extinguisher that can tackle such a toxic fire - and prevent it from re-igniting - is called LFX.
LFX lithium fire extinguishers contain Aqueous Vermiculite Dispersion (AVD), a foam that sticks to battery surfaces and absorbs their heat to stop the thermal runaway effect. They can also put out secondary Class A fires caused by the initial explosion.
