With more than five billion passengers transported in 2025, the commercial aviation network carried an estimated 20 to 25 billion Portable Electronic Devices (PEDs). The risk of lithium battery fire is a serious safety threat as illustrated by in-service experience including the total loss of aircraft due to fires caused by PED lithium batteries.
The risk of lithium battery fire is heightened by the widespread use of PEDs such as mobile phones, tablets, cameras, powerbanks, and e-cigarettes. Recent studies indicate that e-cigarettes and powerbanks account for approximately 60% of lithium battery fires.
Addressing this systemic risk effectively requires a proactive safety culture across the entire air transport system. Aviation safety relies on collaboration and the transparent sharing of safety initiatives and lessons learned among airlines, regulators, airport authorities, ground service providers, and passengers.
A significant part of this collaborative safety culture must extend to the travelling public. The need for enhanced passenger awareness becomes a critical focus for ensuring flight safety. To that end, EASA published a Safety Information Bulletin in May 2025, and the FAA website has a Lithium Battery Resources website page. Both highlight the need to inform and educate passengers about the risks and limitations associated with the transport and use of lithium battery-powered devices on board aircraft.
It remains essential to consistently review and adhere to the latest procedures. Global organisations such as ICAO and IATA, along with regulators like the FAA and EASA, frequently update their guidance to support all stakeholders. These resources are essential for staying informed about the evolving challenges related to the air transport of lithium batteries.
While industry measures, such as crew training for battery fires, are essential, a collective commitment from passengers is equally important. The entire industry must work together to anticipate and mitigate these risks, ensuring every passenger understands their role in keeping everyone safe.
