Safety issues may affect lithium-ion battery transportation.
United Airlines became the second main airline in the United States, which refused to wholesale the supply of lithium-ion batteries due to high risks.
Delta Airlines ceased such deliveries in February. According to officials, it is lithium-ion batteries that are to blame for the recent fires that led to the death of 4 crew members.
The Federal Aviation Administration conducted an experiment with a container with 5000 cells and a cartridge heating element that simulated the overheating of one of the batteries. This caused a chain reaction in the remaining batteries with the temperature rising to 600 ° C. An explosion followed the heating, knocking out the container doors and throwing fire on the transport compartment.
The repetition of this test with the use of a fire extinguishing agent revealed no changes, the explosion occurred again.
According to United Airlines, the reason for the refusal is at risk for customers, for their things and for the environment.

There were several emergency situations in which batteries could be the cause of fires. [one]
American Airlines stopped taking some types of lithium-ion batteries in February. They accept small packs of batteries connected in one container. But this raises questions from a safety point of view due to the concentration of a large number of batteries together in one container.
At the moment, the main problem is the need to develop a new, safe way to transport batteries and batteries containing lithium.
Approximately 4.8 billion cells were manufactured in 2013, the expected production for 2025 is 8 billion cells.
Tests also revealed that lithium-metal batteries, which are not rechargeable, and devices like cameras and calculators light up more often than other versions. The UN banned the transportation of such batteries on passenger aircraft last year; the ban came into force in January.
About 10% of the 2.5 billion lithium metal batteries are transported annually by air. Lithium-ion batteries are shipped much more often by aircraft.
Delivery of equipment that includes lithium batteries, such as laptops, is still performed by the above three airlines.
