High-pressure water mist lithium battery energy storage

Can water mist be used to extinguish lithium-ion batteries?

CONCLUSIONS Lithium-ion batteries pose significant fire risks and the development of fire extinguishment systems for LiBs has not been sufficiently established to provide a satisfactory level of security in the event of a fire. This paper highlights that water mist may be an effective method of extinguishment of LiB fires.

Can lithium-ion battery fires be suppressed with a rapid water mist cooling system?

The prompt and effective suppression of lithium-ion battery (LIB) fires presently remains a challenge. In the present work, apparatus is constructed to investigate the extinguishment and cooling effectiveness of a single LIB dodecafluoro-2-methylpentan-3-one (C 6 F 12 O) suppression and rapid water mist cooling system.

Does water mist reduce the flame of a battery pack?

By analyzing the simulation results of different fire extinguishing strategies, the main factors affecting the suppression of the flame of the battery pack by the water mist are clarified. The main research results are as follows:

How does water mist affect battery cooling?

The cooling rate was influenced by the delay period between application of C 6 F 12 O and water mist, with a longer delay period giving a reduced cooling effect. Water mist cooling at various working pressures (1, 2, and 3 MPa) demonstrated a reduction in peak battery temperature with increased working pressure.

What is high pressure water mist protection?

"High pressure water mist protection provides good heat mitigation at module level in addition to providing full battery space protection from external fires. It also has good gas absorption and gas temperature reduction capabilities.” (Source: DNVGL Technical Reference for Li-Ion Battery Explosion Risk and Fire Suppression, 1144K9G7-12.

How much water does a lithium battery use?

Jiang et al. used Pyrosim software to carry out a simulation study on a runaway battery fire extinguishing. They found that the recommended water consumption range for fire simulation of air transport lithium batteries on an experimental scale of water mist suppression was 243–591 mL.
