5. Conclusions A parametric study of the explosion resulting from gases vented from the failure of lithium-ion batteries (LIBs) is undertaken in this study, and the effects of various parameters such as the vent size, battery chemistry, and the state of charge (SoC) on the EVA and NFPA reduced pressure are scrutinized.
The incidence of reported LIB fires is somewhere in the vicinity of one in one million and one in 10 million units . While the probability of a LIB fire on face value does not fit within the realms of a high-risk item, the hazard arises from the sheer volume of lithium batteries being used globally.
Specifically, the exposure of LIBs to abnormal operating circumstances may initiate a series of self-sustaining exothermic reactions inside the enclosure of a battery, thereby significantly increasing the internal temperature and pressure of the battery cell.
It was reported that the burning process of the LIBs exhibited four distinct stages: the heating stage, the cracking of the safety vent, battery ignition, and TR. The data of time and temperature to ignition and TR are presented in Table 7.
The batteries have the maximum pressure at 100% SoC which also reduced as the SoC decreased. This result, therefore, shows that the severity of the explosion resulting from a LIB failure is more intense when the battery has higher energy stored in it. Fig. 7.
Based on this review, the following conclusions are formulated: The chemical composition of the battery changes both the likelihood of a LIB going into TR and the consequence (energy magnitude of the resultant HRR) for the resultant fire/explosion.
