Study on the minimum extinguishing concentration of C6F12O for extinguishing synthesis gas flame of lithium-ion battery

Accidents involving lithium-ion batteries in electric vehicles frequently occur, which limits the industry's growth and makes it more challenging to build the energy supply sustainably. In this study, we add a liquid-phase input end to make cup burner suitable for the fire-extinguishing test of liquid-phase fire-extinguishing agent and test the minimum extinguishing concentration (MEC) of C6F12O on the synthesis gas of lithium-ion battery. Furthermore, the physical effects and chemical effects of C6F12O on lithium-ion battery syngas fire are quantified by the perfect stirred reactor (PSR) model. The result shows that the fire-extinguishing effect of C6F12O on lithium-ion battery fire mainly depends on the physical effect of cooling.

In this study, a liquid-phase input end is added to the cup burner to test the fire-extinguishing effect of C6F12O on lithium-ion battery syngas. The minimum extinguishing concentration (MEC) of C6F12O is determined, and the physical and chemical effects of C6F12O on lithium-ion battery syngas fire are quantified using the perfect stirred reactor (PSR) model. The results indicate that the fire-extinguishing effect of C6F12O on lithium-ion battery fire is mainly due to its physical cooling effect.
