Why Is Lithium Not Allowed On Airplanes?

Have you ever wondered why you can’t bring your laptop or phone charger on an airplane? It’s because of the lithium batteries that power them. Lithium batteries can produce dangerous heat levels, cause ignition, short circuit very easily, and cause inextinguishable fires. That’s why renowned aviation authorities, including those in the USA, have banned lithium batteries when traveling.

So, why is lithium not allowed on airplanes?

There are a few reasons why lithium batteries are not allowed on airplanes. Firstly, they can produce dangerous heat levels, which could potentially cause ignition or a fire. Secondly, they can short circuit very easily, which could again lead to a fire. And finally, they are very difficult to extinguish once they catch fire, meaning that any fire they cause could quickly get out of control. All of these dangers are magnified when lithium batteries are kept in a confined space like an airplane, which is why renowned aviation authorities have banned their use during travel.

Let’s dig into it and see what we can learn.


  • Lithium batteries are dangerous because they are sensitive to high temperatures, can easily catch fire if damaged or overheated, and the chemicals in them can be corrosive.
  • Lithium batteries work by using a cathode, anode, and electrolyte to create a flow of electrons. The lithium ions move from the cathode to the anode during a discharge cycle, and back to the cathode during a recharge cycle.
  • The benefits of lithium batteries include a longer life cycle, higher energy density, low maintenance, and minimal wasted energy.
  • No, lithium batteries are not recyclable.
  • Some alternatives to powering devices with lithium-ion batteries include solar power, wind-up chargers, and fuel cells.

Why Are Lithium Batteries Not Allowed On Planes?

There are several reasons why lithium batteries are not allowed on planes. First, they can pose a fire hazard if they are damaged or defective. Additionally, recalled lithium batteries may also be a safety concern due to their potential for overheating or catching on fire. Finally, even when lithium batteries are not a safety hazard, they may still be prohibited from being carried in carry-on or checked baggage by individual airlines.

What Happens If You Have A Lithium Battery In Checked Luggage?

Lithium ion batteries are not allowed in checked baggage because they can pose a fire risk. If a lithium battery is in checked luggage, it will not be screened and could enter the cargo hold of the aircraft without any safety precautions. This could lead to a fire on the plane if the battery were to short circuit.

Are You Allowed To Take Lithium Batteries On A Plane?

Yes, you are allowed to take lithium batteries on a plane, as long as they are spare (uninstalled) batteries and are carried in carry-on baggage only. Up to two larger lithium ion batteries (101–160 Wh) or lithium metal batteries (2-8 grams) may be carried with airline approval.

Can I Take Lithium Batteries On A Plane 2022?

Yes, you can take lithium batteries on a plane in 2022. However, there is a limit of two spare batteries per person for the larger lithium ion batteries (101–160 watt hours per battery).

What Devices Have Lithium Batteries?

Devices that have lithium batteries include Bluetooth headsets and headphones, mobile phones, laptops, tablets, cameras, strobe heads, vaping devices, power banks, and cell phone battery charging cases.

What Are The Consequences Of Accidentally Leaving A Battery In Checked Luggage?

If you leave a battery in your checked luggage, it could be confiscated, and you may be asked to leave the premises and face a civil penalty.

Can I Bring Aa Batteries On A Plane?

You can bring regular alkaline AA batteries on a plane in either carry-on or checked baggage, but rechargeable AA NiMH or lithium ion batteries must be in carry-on baggage only.


  • What Is A Lithium Battery?: A lithium battery is a type of battery that uses lithium ions in its electrochemistry. Lithium batteries are rechargeable, and have a higher energy density than other types of batteries.
  • Can I Bring Batteries In My Checked Luggage?: You can bring batteries in your checked luggage, but spare lithium batteries and power banks must be removed from carry-on bags and kept with the passenger.

Final Word

So there you have it! Be sure to avoid packing any lithium batteries in your carry-on or checked luggage when flying. And if you must travel with them, be sure to keep them in a safe and secure place.
