6 FAQs about [Battery production hydrofluoric acid accounts for the proportion]

What happens if a Li-ion battery fire releases hydrogen fluoride?

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. Hydrogen fluoride mixes readily with water forming hydrofluoric acid. For all practical purposes, they are considered the same chemical.

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.

Can we measure HF from Li-ion batteries under abuse conditions?

Although a number of qualitative and semi-quantitative attempts have been made in order to measure HF from Li-ion batteries under abuse conditions, most studies do not report time dependent rates or total amounts of HF and other fluorine containing gases for different battery types, battery chemistries and state-of-charge (SOC).

How much HF is released from Li-ion batteries?

The amounts of HF released from burning Li-ion batteries are presented as mg/Wh. If extrapolated for large battery packs the amounts would be 2–20 kg for a 100 kWh battery system, e.g. an electric vehicle and 20–200 kg for a 1000 kWh battery system, e.g. a small stationary energy storage.

Does HF react with hydrofluoric acid?

The toxicity of HF (hydrogen fluoride) and the derivate hydrofluoric acid is well known while there is little toxicity data available for POF3,(phosphoryl fluoride) which is a reactive intermediate that will either react with other organic materials or with water finally generating HF.

Is hydrofluoric acid harmful or toxic?

Hydrofluoric acid is a highly toxic and extremely corrosive solution of hydrogen fluoride in water. It can cause severe chemical burns if it comes into contact with our skin or eyes.
