FCL-X is a water-based, PFAS-free lithium-ion fire extinguishing agent from Full Circle Lithium Corp. made specifically for lithium-ion battery fires.
It’s designed to stop thermal runaway, reduce toxic gas release, and prevent reignition - something traditional agents like water or foam can’t do.
Tested by SafeLabs and certified to the Dutch NTA 8133 standard, as well as fire suppression certification testing outlined in UL 9540A 4th edition and UL 711 8th edition, FCL-X has been proven in multiple real-world EV fires and industrial training burns and been given a UL Class A Certificate of Compliance.
FCL-X is available in canisters as small as 20 ounces up to 25 gallons, with bulk refill containers up to 275 gallons.
Lithium-ion battery fires are complex and dangerous. They involve intense heat, toxic gas release, and the risk of reignition - even after the flames are out. FCL-X is designed to stop these fires at the source by addressing the unique chemical reactions happening inside the battery.
FCL-X soaks into the battery structure, reaching deep into cells that are undergoing thermal runaway. This direct contact helps interrupt the chain reaction before it spreads to other cells in the battery pack.
As a water-based agent, FCL-X cools the fire quickly, reducing the heat energy driving the reaction.
Lower temperatures slow down chemical reactions, contain the spread, and give responders control.
Lithium-ion fires release toxic gases - including hydrogen fluoride, one of the most dangerous byproducts of battery fires.
FCL-X chemically reacts with these gases to form non-hazardous salts, reducing the danger to people on scene.
FCL-X interrupts the lithium oxidation process that fuels the fire and generates flammable hydrogen gas. By slowing this process, it limits the risk of gas buildup and secondary explosions.
Even after the flames are out, a battery can reignite minutes or even hours later. FCL-X creates a protective barrier that helps stabilize the battery and prevent dangerous flare-ups.
