Experimental Study on the Bundle Lithium-Ion Batteries Fire

In this paper, a report is given on an experimental study of the combustion characteristics of six bundle lithium-ion batteries in a calorimeter. Several parameters including mass loss, heat release rate, surface temperature and heat flux distribution were measured to evaluate the hazards. The experimental results show that the lithium-ion batteries undergo fierce combustion processes. The total mass loss of six lithium-ion batteries fire is 67.8g, and the effective heat of the fire is 7.06 kJ/g. The highest temperature of the batteries fire is 816.9 °C and the maximum heat flux is 0.68 kW/m 2 .The results provide scientific basis for the development of fire protection measures during the usage, storage and distribution of primary lithium batteries.
