Lithium-ion batteries can catch fire or explode if they are damaged or overheated. These batteries are used in many devices, including cell phones, laptops, e-bikes, and electric vehicles. They can be dangerous because they:
Heat up quickly
Lithium-ion batteries can reach temperatures of up to 2012°F in about a second.
Release toxic gases
Lithium-ion battery fires can release toxic gases like carbon monoxide, carbon dioxide, hydrogen chloride, and hydrogen fluoride.
Cause thermal runaway
A self-sustaining chemical reaction can occur inside the battery, which can spread to other batteries.
Don't produce much smoke
Lithium-ion batteries don't produce much smoke in the early stages of failure.
To avoid lithium-ion battery fires, you can:
Buy batteries from reputable manufacturers
Store batteries in a cool, dry place
Use a charger with the correct voltage
Stop charging the battery when it's full
Use charging equipment that's compatible with your device
Stop using a device if the battery shows signs of damage
Have repairs done by a qualified professional
Follow proper storage, charging, and discarding procedures
If you notice a lithium-ion battery getting warm, bulging, or discoloring, you should notify the flight crew immediately
