Lithium-Ion Battery Fire Extinguishing Device

In China,FUXEON®'s lithium-ion battery fire extinguishing device is based on completely independent intellectual property rights and self-research and development, representing top-tier technology in the domestic market for liquid fire extinguishing agent intelligent fire protection systems. It has been widely applied in many locations in China and has achieved excellent fire extinguishing effects when lithium battery fires occur.

Our lithium-ion battery fire extinguishing device mainly includes an automatic sprinkler system, a smoke and sound/light alarm system, a temperature sensing system, with coverage areas ranging from 40㎡ to 560㎡. It is a systematic fire extinguishing device that requires layout based on actual conditions. You only need to provide the covered area, and we can provide a specific installation plan.

Operation method:

1. Once the smoke detector detects smoke, it will immediately activate an audible and visual alarm, emitting a high-decibel alarm sound to notify on-site personnel to evacuate and to notify security personnel to cut off the power and prepare for a fire.

2. When the air temperature in the fire area reaches 70°C, the sensor will activate the solenoid valve in the area where the self-igniting battery is located, and spray the agent through a special nozzle.

3. In extreme circumstances (such as system power failure or automatic control failure), the equipment is equipped with a mechanical emergency manual pull ring as a last resort. The pull ring directly controls the release valve of the extinguishing agent through a mechanical linkage device, ensuring that the fire extinguishing function can still be activated in the event of a complete power outage. After pulling the pull ring, the dedicated nozzles in the area where the self-igniting battery is located will simultaneously spray UPA extinguishing agent to quickly suppress and extinguish the fire.

Fire extinguishing principle:

The lithium-ion battery fire extinguishing device uses our company's UPA fire extinguishing agent, which has suspension polymerization technology. It is an extremely powerful free radical scavenger that can reduce the reaction of hydroxyl and hydrogen free radicals in the burning material during the fire extinguishing process.Combustion is the result of free radical collisions generating energy.

This agent can capture free radicals the moment they appear, preventing new free radicals from reacting and fundamentally blocking combustion to prevent reignition. Furthermore, it enhances the binding properties of metals, binding together some of the more reactive metals (such as sodium, magnesium, aluminum, and lithium), rapidly blocking combustion and achieving a remarkable flame-retardant effect.

Its fire extinguishing process is as follows: cooling → penetration → capture → hibernation → blockage

FAQ

Q：Why can’t conventional CO₂ or dry powder extinguishers put out lithium-ion battery fires completely?

A：Lithium-ion battery fires are electrochemical thermal runaway fires, not ordinary Class A/B fires. CO₂ only cools the surface briefly and cannot stop internal chemical reactions; dry powder fails to cool the core and leaves conductive/corrosive residues. Both often lead to reignition within seconds or minutes.

Q：What makes your lithium-ion battery fire extinguishing device different from ordinary fire extinguishers?

A：Our device uses AVD (Aqueous Vermiculite Dispersion) or specialized water-based lithium-ion formulations. It delivers rapid core cooling (stops thermal runaway) + thermal barrier encapsulation (prevents spread/reignition) + non-toxic & residue-free performance. It penetrates battery gaps to cool hidden hotspots, the key to stopping Li-ion fires permanently.
