Devices powered by lithium-ion batteries are overheating more often during airline flights, posing a potential risk to passengers and crew. These incidents have been on the rise, with a 28% increase from 2019 to 2023, according to a recent report by UL Standards.

E-cigarettes have been identified as the most common source of overheating, based on reports from 35 airlines. In many cases, thermal runaway events, a term used to describe battery overheating, have occurred near the passenger who brought the device on board.

The implications of lithium-ion battery incidents can be serious. In one instance, a smoking laptop in a passenger’s bag forced the evacuation of a plane at San Francisco International Airport. Another flight had to make an emergency landing after a battery caught fire in an overhead bin.

Despite federal rules prohibiting e-cigarettes and chargers with lithium-ion batteries in checked bags, a significant portion of passengers admit to flouting these regulations. This poses a challenge for airline safety as fires in the cargo hold may go undetected.

The Federal Aviation Administration has reported a significant increase in thermal-runaway incidents on planes in recent years, highlighting the need for enhanced safety measures. UL Standards’ study underscores the importance of addressing the risks associated with lithium-ion batteries on airplanes.

As technology continues to evolve, it is crucial for regulators, airlines, and passengers to collaborate in ensuring a safe travel environment. By following established guidelines and being mindful of the risks, we can mitigate the dangers posed by lithium-ion batteries on airplanes.
