Perfluorohexanone energy storage fire protection

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 protect spaces housing electrical systems [18, 19].

Does a plunger type perfluorohexanone (c 6 F 12 o) fire extinguishing device work?

In this study, a plunger type perfluorohexanone (C 6 F 12 O) fire extinguishing device was developed, and key components such as gas generating device and puncture valve were improved. The 271 Ah lithium iron phosphate battery was used to verify the fire extinguishing efficiency and environmental adaptability of this device in extreme environments.

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 perfluorohexanone spray last?

The duration of perfluorohexanone 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. After the extinguishing, the intervening ignition was carried out with an open flame, and there was no re-ignition phenomenon.

Can perfluorohexanone suppress lithium-ion battery fires?

Perfluorohexanone is used widely to protect spaces housing electrical systems [18, 19]. The agent has been demonstrated to have an outstanding fire extinguishment performance and a minimal environmental impact [20, 21]. Therefore, the perfluorohexanone was selected as the potential inhibitory medium for suppressing lithium-ion battery fires .

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.
