6 Frequently Asked Questions about “Lithium battery heats up and smokes”

Are lithium-ion battery fires dangerous?

Lithium-ion battery fires generate intense heat and considerable amounts of gas and smoke. Although the emission of toxic gases can be a larger threat than the heat, the knowledge of such emissions is limited.

Can lithium ion battery smoke affect human health?

Exposure to lithium-ion battery smoke can adversely affect human health. Lithium-ion batteries contain various chemicals, including lithium, cobalt, and solvents. When these batteries experience damage, overheating, or malfunction, they can release toxic smoke.

What chemicals are released when a lithium-ion battery emits smoke?

Understanding what chemicals are released when a lithium-ion battery emits smoke requires examining the specific substances that are generated during thermal runaway and combustion. Hydrogen fluoride is a toxic gas released during the thermal decomposition of lithium-ion batteries.

Why do lithium-ion batteries fire?

Lithium-ion batteries can reignite due to thermal runaway, where temperature and pressure build-up within the cell causes it to catch fire again. Remaining vigilant ensures that any potential risks are addressed promptly. Being aware of these emergency procedures can save lives and reduce hazards associated with lithium-ion battery fires.

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.

Do lithium-ion batteries release smoke gas during thermal runaway?

By analyzing the smoke gas emission, this work has shown that 100 % charged cylindrical lithium-ion batteries release a likely smoke gas quantity of up to 27 mmol Wh −1 during the thermal runaway (see Fig. 5). Individual, unverifiable measurements even yield values of up to 48 mmol Wh −1.
