[0002] With the rapid development of new energy vehicles and lithium battery technology, lithium batteries, as the main energy storage devices, are widely used. However, lithium batteries may experience thermal runaway during charging, discharging, or under the influence of the external environment, leading to fire or explosion accidents, seriously threatening personal safety and property safety. Traditional fire extinguishing agents such as water and foam fire extinguishing agents are highly effective in extinguishing Class A and Class B fires, but their fire extinguishing effect on lithium battery fires is limited. For new energy fires, dedicated chemical supply equipment is required.
