What is the best fire extinguishing agent for lithium ion batteries?

Ideal temperature-sensitive hydrogel extinguishing agent fire extinguishing schematic. Surfactants are an essential component of the extinguishing agent formula for lithium-ion batteries. In the patents for the invention of the extinguishing agent, both hydrocarbon and fluorocarbon non-ionic and anionic surfactants are used.

Is a lithium battery a fire extinguisher?

Subsequently, Samsung SDI and Robert Bosch GmbH jointly developed a similar concept in 2012, a gel-based lithium battery specialized fire extinguishing and flame-retardant agent, which utilizes the combined effects of alkaline earth metal carboxylates and swellable polymers (No. US20140034864A1, Fig. 18 ).

Can surfactants be used in lithium-ion batteries & extinguishing agents?

While newer, more efficient Lithium-ion batteries (LIBs) and extinguishing agents have been developed to reduce the occurrence of thermal runaway accidents, there is still a scarcity of research focused on the application of surfactants in different LIBs extinguishing agents, particularly in terms of patented technologies.

What extinguishing agents were used in a lithium cobalt-acid battery fire?

Carbon dioxide, ABC dry powder, and 3% aqueous film-forming foam extinguishing agents were all effective in extinguishing the open flame of 18,650 lithium cobalt-acid battery fires, but re-ignition occurred after extinguishing the fire, and the time of re-ignition was proportional to the cooling capacity of the extinguishing agent .

Does water mist extinguish lithium battery fires?

Fine water mist extinguishing agents have obvious advantages over ultra-fine dry powder extinguishing agents . Water can successfully extinguish lithium battery fires in electric vehicles, but there are shortcomings such as high water consumption and long extinguishing times.

What makes a good Lib extinguishing agent?

The ideal LIBs extinguishing agent needs to be able to extinguish battery fires and cool the battery, but also needs to be able to absorb toxic gases such as HF and flammable and explosive gases such as H 2 and CO.
