Energy storage perfluorohexanone fire extinguishing

What is perfluorohexanone fire extinguishing agent?

The perfluorohexanone fire extinguishing agent has attracted the attention of the industry because of its environmental friendliness and good performance in suppressing lithium-ion battery fires . Perfluorohexanone is used widely to pro-tect spaces housing electrical systems [18, 19].

Does perfluorohexanone fire extinguish lithium ion batteries?

Wang et al. have studied the fire extinguishing effects of perfluorohexanone on lithium-ion batteries. The study showed that perfluorohexanone could effectively extinguish the fire of lithium-ion batteries, and extinguished the open flame within 30 s . Liu et al. tested the application of perfluorohexanone to single LIB cells.

What are the physical properties of perfluorohexanone?

Physical Parameters Perfluorohexanone is a fluorinated ketone compound. It is a colorless, odorless, and easily vaporized liquid fire extinguishing agent at room temperature. No resi-due is left after evaporation. The main fire extinguishing mechanism is chemical suppression and flame cooling.

How long does perfluo-rohexanone spray take to extinguish a fire?

The fire was extinguished within 9 s after the release of the extinguishing agent, which was faster than that of Test 6. The duration of perfluo-rohexanone spray was 45 s. The shorter time to extinguish the fire is mainly because of the rapid increase of internal pressure of fire extinguishing device under high temperature.

How does perfluorohexanone work?

The device is in a storage pressure (perfluorohexanone) when it is not working, and it can be activated with a small current immediately when a fire sig-nal is received. A pressure cavity is formed at the front end of the sealed cavity as a power source, and the perfluorohexanone is atomized by an atomizing nozzle.

How long does perfluorohexanone spray last?

The perfluorohexanone spray duration was 64 s. The reason for this delay is that the internal pressure of the fire extinguishing device rose slowly at low temperatures. After the open flame was extinguished, the ignition was introduced several times with the open flame, but it was not ignited.
