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.
Ji et al. (Ji et al., 2023) established a fire and extinguishing model for lithium-ion battery packs and simulated the suppression of power battery pack fires by fine water mist.
Several standalone battery modules and also a full scale EV were tested by bringing the batteries into a state of thermal runaway, resulting in battery fire. Water was introduced after 15 minutes from the first signs of propagation, to simulate a typical fire service response time.
A report from tests made public by the Swedish Civil Contingencies Agency (MSB) shows that a cutting extinguisher can safely put out a battery fire in a very short time, with minimal use of water and without the risk of re-ignition.
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.
The fire propagation behavior was analyzed from both the battery pack level and the vehicle level. Subsequent fire fighting tests evaluated the fire extinguishing efficiency of different types of EVFE. The TR propagation mechanisms of the full-size commercial battery packs were different from that of small-scale battery modules.

40g new energy fire buster is an aerosol fire extinguisher designed specifically for larger-sized energy storage packs. This product is very thin, only 15mm thick, and very adaptable to the battery pack. The main medium for extinguishing fires is aerosol, which is an extinguishing agent that is solid at rest and gaseous when sprayed.
Scientists have developed a new design for a self-extinguishing rechargeable battery that can prevent fires and explosions caused by overheating.
Full-scale fire experiments were employed to evaluate the fire extinguishing efficiency of various types of EVFE. Results showed that EVFE could effectively suppress the thermal runaway (TR) of full-size LIB packs in the EVs under these experimental conditions, and the battery packs did not occur re-thermal runaway after EVFE stopped working.
