Prelithiation technology has greatly improved the service life of LiFePO 4 /C battery, but its influence on the combustibility of the battery is still unclear. In this paper, the combustibility of the key components (positive electrode, negative electrode and separator) of LiFePO 4 /C battery with prelithiation technology and conventional LiFePO 4 /C battery are compared, and the differences in combustion parameters(effective combustion heat, total heat release, heat release rate) and smoke parameters(total smoke production, CO yield, CO2 yield, and specific extinction area) between the two types of batteries are analyzed. The results show that the combustibility of the two types of batteries is basically similar, and there is no significant difference. With the decrease of the capacity retention rate, the combustibility and smoke generation of the battery show a downward trend.
