The complete combustion of a 60-Ah lithium iron phosphate battery releases 20409.14–22110.97 kJ energy. The burned battery cell was ground and smashed, and the combustion heat value of mixed materials was measured to obtain the residual energy (ignoring the nonflammable battery casing and tabs) [35 ]. The calculation results are shown in Table 6.
The influence of the combustion state on the heat release performance and voltage of lithium batteries is proposed. The influence of combustion state on energy release and smoke toxicity. Assessment methods for energy and smoke toxicity is proposed. The combustion state does not affect the TR behavior of the battery.
The combustion state does not affect the TR behavior of the battery. heat release rates (HRRs) were analysed during the experiment, and the material 3) can reach 5.38 times the lethal concentration. The HRR and remaining energy of the battery were greatly affected by the combustion states.
The energy changes of the battery system are calculated. The battery fire hazard is evaluated by analysing the combustion characteristics of LIBs in different combustion states. The experimental conclusions can provide reference basis for firefighters to implement firefighting and safety protection strategies. 2. Experimental 2.1. Battery samples
With the commercialisation of lithium-ion batteries (LIBs), battery safety has gained increasing attention. In recent years, battery fires and explosions, such as the explosions of Samsung and Apple mobile phones, burning of BYD taxis, and the spontaneous combustion of Tesla electric car batteries, have been reported at times [1 ].
Few studies have focused on different combustion states. In practical applications, batteries generally have three combustion states: flame burning, flameless smouldering, and explosion.
The energy changes of the battery system are calculated. The battery fire hazard is evaluated by analysing the combustion characteristics of LIBs in different combustion states. …
