Analysis of Toxic fumes emitted during Small Scale Lithium-Ion Battery fires

Lithium-Ion Batteries (LIB) have dominated the energy market for a couple of decades due to their high energy density and long-life cycle. However, several fire accidents in Electric vehicles have raised questions about the safety concerns of Li-ion batteries. Researchers have identified thermal runaways to be the major reason for the fire susceptibility of LIBs. One of the major risks in accidents involving LIB fires is toxic gaseous emissions. Hence, it is necessary to understand the toxic emissions of LIB fires to properly counter them. In this study, small-scale battery fire tests are performed, and the toxic gases will be analyzed using different tools such as FTIR and multi-gas detectors. The results of this study are expected to confirm the presence of hydrocarbons and fluoride emissions such as HF, POF3, etc., in some specific chemistries, and it is expected to study some gases that are unknown to the research community. Based on the results of the study it is recommended to take necessary action for possible fire scenarios in closed spaces and underground mines.
