Dear MEL Topic Readers,
What happens when a device nearly every passenger carries onboard a
plane erupts in smoke and flames
Most portable electronic devices, including mobile phones, tablets, and
laptops, are powered by lithium-ion batteries. They offer high energy density,
a long lifespan, fast charging, and a low self-discharge rate. However,
they are sensitive to temperature extremes and pose safety risks like fire when overheated.
Thermal runaway is a self-perpetuating chain reaction that starts when a
battery overheats due to physical damage, overcharging, manufacturing defects,
or extreme external temperatures. Nowadays, nearly every airplane passenger
brings in or checks in lithium battery-powered devices, and occasionally, they
cause a fire during the flight. The US aviation administration now prohibits passengers
from packing lithium devices in their checked baggage. China bans passengers
from carrying uncertified or over 160Wh power banks on their flights, and South
Korea bans passengers from charging devices on board. As more airlines, especially
low-cost carriers, are eliminating in-flight entertainment, and more passengers
prefer to entertain themselves with their own portable devices, the chances of lithium
battery fires on board are increasing. What should you do if a fire breaks out
during the flight?
Read the article and learn about the risk of lithium-powered devices on
board.
