Lithium Battery Incidents on Airplanes are Increasing

As we all know by now, lithium batteries aren’t going anywhere anytime soon. As beneficial as lithium batteries are, they do come with their share of problems. A while back I authored an article about the dangers of lithium batteries catching fire and how to effectively extinguish and prevent these types of fires.

However, A lithium battery fire becomes more problematic if it happens aboard an aircraft, especially if it happens while in the air. Unfortunately, these types of incidents are becoming more common according to the Federal Aviation Administration (FAA).

Why do Lithium Batteries catch fire?

Lithium batteries can go through a process called thermal runaway, which causes them to catch fire. Thermal runaway results in a rapid increase of battery cell temperature and pressure, accompanied by the release of flammable gas. These flammable gases will often be ignited by the battery’s high temperature, resulting in a fire. This process typically begins with an initial increase in temperature due to external factors like overcharging, overheating, or mechanical damage. As the temperature rises, it triggers additional reactions within the battery, which releases more heat and further increases the temperature.

An Increase in Lithium Battery Incidents Aboard Aircrafts

Data has suggested that there has been an increase in lithium battery fires aboard aircrafts and in airports. According to the FAA, the number of lithium-ion battery fires jumped more than 42% in the last 5 years. Incidents of overheated lithium batteries causing smoke, fire, or extreme heat on aircrafts are now happening at an average rate of more than one per week. In 2022, the FAA reported at least 62 incidents involving lithium-ion batteries on airplanes and in airports, compared to 54 incidents in 2021.

As more personal devices are powered by lithium-ion batteries, the number of these incidents has increased overall in the past decade. For example, in 2014 the FAA reported only nine lithium battery incidents all year. Compare that to last year, when there were nine lithium-battery incidents reported in each of three months: May, July, and August. How do you prevent these incidents from occurring?
