Energy storage cabinet perfluorohexanone

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 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].

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 .

Does perfluorohexanone reduce flaming combustion of ejected battery materials?

Liu et al. tested the application of perfluorohexanone to single LIB cells. The study was to evaluate the ability of perfluorohexanone to suppress flaming combustion of ejected battery materials and effectively cool down the cell after it underwent thermal runaway .

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.

How long does perfluorohexanone 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 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.
