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.
