Customer ServiceAs lithium battery fire is a deep fire, TR will release a large amount of gas, making it difficult for gaseous extinguishing agents to enter the interior of the battery, so in the suppression of lithium battery TR, gaseous extinguishing agents can effectively extinguish the flame, but cannot prevent the continuation of the TR reaction inside the lithium battery, which

Customer ServiceAn overview of the causes of lithium-ion battery fires, what types of extinguishing agents are used when a fire occurs, and how to effectively prevent fires from occurring.
Customer ServiceThe 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.
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.
Based on this, the three-phase synergistic extinguishing mechanism of gas, liquid and solid under the NAM method is revealed, which provides an important reference for the design of extinguishing agents and extinguishing methods for lithium-ion batteries. 1. Introduction
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.

Gas fire-extinguishing agents such as Halons, HFC-227ea, CO 2 and Novec 1230 are beneficial to integrity protection of battery system during the fire extinguishing process. However, gas fire-extinguishing agents could not effectively reduce the temperature of 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.
