Liquid nitrogen energy storage fire extinguishing system

Liquid nitrogen extinguishing systems offer an extremely efficient means of fire suppression, making them particularly suitable for lithium battery energy storage systems.

This paper investigates the synergistic cooling effect of LN and WM, and evaluates the advantages and disadvantages of synergistic fire extinguishing strategies with different release sequences, aiming to provide new insights for the fire suppression and cooling protocols of LIBs.

Liquid nitrogen extinguishing systems offer an extremely efficient means of fire suppression, making them particularly suitable for lithium battery energy storage systems. Liquid nitrogen’s unique physical properties, such as its extremely low temperature and rapid evaporation, allow this technology to rapidly cool flames down while .

Research on Fire Protection System Technology for Lithium Battery Based on Liquid Nitrogen Fire Extinguishing.PDF. , 。. .

Among these fire-extinguishing agents, liquid nitrogen possesses the best cooling ability, followed by C 6 F 12 O, HFC-227ea, CO 2, dry powders and aerosol. With the further development of LIB towards higher voltage and higher energy, the insulation of fire-extinguishing agents has become an essential parameter to be considered first.

6 FAQs about [Liquid nitrogen energy storage fire extinguishing system]

Is liquid nitrogen a good fire extinguisher?

Liquid nitrogen has many advantages of low cost, non-toxic and excellent cooling ability, which is very suitable for extinguishing LIBs fire. However, the storage and transportation problems are still obstacles to the application of liquid nitrogen.

Does liquid nitrogen suppress thermal runaway in lithium ion batteries?

Thermal runaway (TR) and resultant fires pose significant obstacles to the further development of lithium-ion batteries (LIBs). This study explores, experimentally, the effectiveness of liquid nitrogen (LN) in suppressing TR in 65 Ah prismatic lithium iron phosphate batteries.

Can liquid nitrogen extinguish LFP res?

of liquid nitrogen for extinguishing LFP res, noting that while it can douse visible ames, it fails to impede thermal runaway spread. Various studies demonstrate that dry powders and hot aerosols can suppress open battery res but do not prevent re-ignition.

Does liquid nitrogen suppress Lib fire?

Some studies have found that liquid nitrogen has a good suppression effect on LIBs fire because of its excellent cooling capacity [81, 82]. The suppression mechanisms of liquid nitrogen on LIBs fire are shown in Figure 8. Huang et al. firstly investigated the suppression, delaying and cooling effect of liquid nitrogen on TR of LIBs.

How effective is liquid nitrogen in preventing fires?

Previous studies have demonstrated liquid nitrogen (LN) effectiveness in suppressing oil pool fires , coal spontaneous combustion , and tunnel fires . As shown in Fig. 1, LN has a strong cooling and asphyxiating effect on TR and fires resulting from it .

Which fire extinguishing agent is not suitable for Lib fire?

Similar to these gaseous fire-extinguishing agents, solid fire-extinguishing agents such as dry powder are not suitable for extinguishing LIB fires due to their poor cooling effect. While C 6 F 12 O and liquid nitrogen possess excellent extinguishing and cooling capacity, which are suitable for extinguishing LIBs fire in confined environment.
