Research progress of new fire extinguishing agents for suppressing lithium battery fires
This paper introduces the basic structure and working principle of lithium-ion batteries,analyzes the trigger mode of thermal runaway of lithium-ion batteries,and focuses on the analysis of fire extinguishing mechanism,fire extinguishing agent preparation and fire extinguishing performance of three new lithium-ion battery fire extinguishing agents,namely hydrogel fire extinguishing agent,perfluorohexanone fire extinguishing agent and dry water fire extinguishing agent.On this basis,this paper summarizes the advantages and disadvantages of the three fire ex-tinguishing agents,and provides ideas for the improvement of the fire extinguishing effect and performance of the fire extinguishing agent in the future.It is of great significance to improve the safety of lithium-ion batteries and promote the development and applica-tion of electrochemical energy storage technology.
