6 FAQs about [Lithium battery fluorine gas]

Why is fluorine important in lithium ion batteries?

Do lithium-ion batteries emit HF during a fire?

Our quantitative study of the emission gases from Li-ion battery fires covers a wide range of battery types. We found that commercial lithium-ion batteries can emit considerable amounts of HF during a fire and that the emission rates vary for different types of batteries and SOC levels.

How much hydrogen fluoride can a battery generate?

The results have been validated using two independent measurement techniques and show that large amounts of hydrogen fluoride (HF) may be generated, ranging between 20 and 200 mg/Wh of nominal battery energy capacity. In addition, 15–22 mg/Wh of another potentially toxic gas, phosphoryl fluoride (POF 3), was measured in some of the fire tests.

Is hydrogen fluoride a risk for a Li-ion battery fire?

The release of hydrogen fluoride from a Li-ion battery fire can therefore be a severe risk and an even greater risk in confined or semi-confined spaces. This is the first paper to report measurements of POF 3, 15–22 mg/Wh, from commercial Li-ion battery cells undergoing abuse.

Are lithium ion batteries flammable?

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.

Are Li-ion batteries flammable and toxic?

5. Conclusion The off-gas from Li-ion battery TR is known to be flammable and toxic making it a serious safety concern of LIB utilisation in the rare event of catastrophic failure. As such, the off-gas generation has been widely investigated but with some contradictory findings between studies.
