How To Put Out The Fire Of Li Cell — Ultrahigh Power Density Thin Film Battery

From:CTECHI GROUP Limited     Release time:2019-01-08

Overview:When lithium battery ignition needs fire extinguishing treatment, the following schemes are carried out. 1. If a small fire occurs and the flame does not spread to the high-pressure battery, carbon dioxide or ABC dry powder extinguisher can be used to extinguish the fire. 2. When thoroughly checking the fire situation, do not contact any high-voltage components, always use insulation tools for inspection.

Lithium Battery Fire Extinguishing Scheme


When lithium battery ignition needs fire extinguishing treatment, the following schemes are carried out.


1. If a small fire occurs and the flame does not spread to the high-pressure battery, carbon dioxide or ABC dry powder extinguisher can be used to extinguish the fire.


2. When thoroughly checking the fire situation, do not contact any high-voltage components, always use insulation tools for inspection.


3. If high-voltage batteries are bent, twisted or damaged in a fire, they will become disfigured or suspected of battery problems. So the amount of water used for fire extinguishing should not be too small, and the amount of water used for fire extinguishing should be enough.

4. Battery fire may take 24 hours to completely extinguish. The use of thermal imaging cameras ensures that high-voltage batteries are completely cooled before the end of the accident. If there is no thermal imaging camera, it is necessary to monitor whether the battery will reburn. Smoke indicates that the battery is still hot, and monitoring should be maintained until at least an hour after the battery is no longer smoking.


The Emergency Rescue Manual of General Volanda in the United States guides the fire extinguishing of electric vehicles as follows: if the battery reaches a high enough temperature, leaks and releases electrolytes, the electrolyte must be inflammable. This requires a large amount of water to cool batteries and fire extinguishing, because DC and AC systems are not grounded, firefighters can use safe water as the main fire extinguishing agent, and there is no risk of electric shock. ABC dry powder extinguisher will not extinguish battery flame. Firefighters should avoid direct internal contact in fire extinguishing or relief operation of any high-pressure components, which can potentially lead to electric shocks.
