New Energy Lithium Battery Fire Extinguishing

Can a cutting extinguisher be used in a lithium-ion battery fire?

Cold Cut Systems used a cutting extinguisher (Standard Cobra lance) in the pilot study with good results. It was determined there was enough evidence to motivate further studies and tests to develop guidelines for offensive extinguishing efforts of lithium-ion battery fires. This demonstration is an activity within the scope of this work.

Do lithium-ion batteries have a fire extinguishing effect?

The fire extinguishing effect of the fire extinguishing material prepared in this article for lithium-ion batteries is significantly improved compared to traditional ABC dry powder fire extinguishing agents, but the cooling effect of batteries after thermal runaway needs to be improved.

Does dry powder fire extinguishing agent affect lithium-ion battery with thermal runaway?

The results show that the ABC dry powder fire extinguishing agent modified by microcapsule has a certain cooling effect on the lithium-ion battery with thermal runaway, and the cooling effect is good.

Which fire extinguishing agent is used in a lithium ion traction battery?

German motor vehicle inspection association (DEKRA) reported several kinds of water-based fire-extinguishing agents such as water, F-500 and a gelling agent used in extinguishing lithium-ion traction batteries fires. The flame of power LIBs was rapidly extinguished by 1% F-500 within merely 7 s.

Does ABC dry powder fire extinguishing agent inhibit lithium-ion battery fires?

Under the experimental conditions of the NA group, the flame area significantly decreased compared to the first two groups, reaching a maximum of 1600.76 cm 2, indicating that ABC dry powder fire extinguishing agent has an effective inhibitory effect on lithium-ion battery fires.

How do fire extinguishing materials affect the temperature of a battery?

As can be seen from the figure, under the conditions of applying different fire extinguishing materials, the curve trend is roughly the same, and the temperature first slowly increases, then accelerates, and finally gradually decreases, but the maximum temperature that can be achieved on the battery surface is different.
