Under certain severe failure conditions, lithium-based rechargeable cells can emit gases which may be harmful to humans and/or may form a combustible mixture in sufficient concentrations. Examples may include, but are not limited to, carbon monoxide (CO), carbon dioxide (CO2), hydrogen (H2), organic solvent vapors and hydrogen fluoride (HF).
Although the emission of toxic gases can be a larger threat than the heat, the knowledge of such emissions is limited. This paper presents quantitative measurements of heat release and fluoride gas emissions during battery fires for seven different types of commercial lithium-ion batteries.
That brings us to the aftermath of the fire – and another often-overlooked hazard: toxic fumes. When lithium-ion batteries catch fire in a car or at a storage site, they don’t just release smoke; they emit a cocktail of dangerous gases such as carbon monoxide, hydrogen fluoride and hydrogen chloride.
The electrolyte in a lithium-ion battery is flammable and generally contains lithium hexafluorophosphate (LiPF 6) or other Li-salts containing fluorine. In the event of overheating the electrolyte will evaporate and eventually be vented out from the battery cells. The gases may or may not be ignited immediately.
When a lithium-ion battery fire breaks out, the damage can be extensive. These fires are not only intense, they are also long-lasting and potentially toxic. What causes these fires? Most electric vehicles humming along Australian roads are packed with lithium-ion batteries.
The hydrogen content of the released gases can give rise to vapour cloud explosion risks which have the potential to cause significant damage. TT advocates a range of measures to mitigate the risks. A prudent starting point would be to perform a fire risk assessment, considering the specific hazards presented by lithium-ion batteries.
It may often be safer to just let a lithium battery fire burn, as Tesla recommends in its Model 3 response guide: Battery fires can take up to 24 hours to extinguish. Consider allowing the battery to burn while protecting exposures. This could explain why Tesla advised authorities in Bouldercombe to not put out the blaze.
