Airlines stop accepting rechargable battery shipments due to fire risk - lithium ion battery manufacturers

WASHINGTON-In the face of growing evidence that some of the world's largest airlines are banning the bulk shipment of rechargeable batteries that could have disastrous consequencesflight fires.
United Airlines became the second largest airline in the United States on Monday for security reasons. S.
The airline has announced that it will no longer accept a large number of rechargeable batteries, also known as lithium batteries.
Ion batteries are used to power all devices from smartphones to laptops to power tools.
On February, Delta quietly stopped shipping in batches with rechargeable batteries. 1.
According to several aviation officials, Air France has also stopped taking bulk shipments of batteries.
Officials at the airline did not immediately respond to inquiries from The Associated Press. The third major United StatesS.
American Airlines carrier has stopped accepting certain types of lithium.
Ion batteries shipped in February. 23.
But the airline is continuing to accept a small packet of batteries that are combined or "overpacked" into a container.
These goods are actually a bigger safety issue because they usually cause tens of thousands of batteries inside a container.
All three airlines said they would continue to accept bulk shipping of equipment equipped with batteries or batteries in the same package as the equipment.
Placing the battery in a device such as a laptop or in the same package as an electric tool creates additional buffering and is believed to provide additional protection, although safety experts say the theory is not yet available
Tests by the Federal Aviation Administration over the past year have shown that when the battery is overheated, it causes other nearby batteries to be short-circuited
The circuit is overheated, resulting in a chain reaction.
When used for heat diffusion, the battery emits explosive gas that accumulates inside the cargo container.
Several tests resulted in violent explosions that blew up the door on the container and then triggered a violent fire.
The latest test was conducted last month at the FAA's technical center in New York City. J.
They confirmed the previous test results and indicated that the overheated battery would continuously discharge the gas that caused the explosion.
Officials familiar with the test said that the gas combination released by the battery varies depending on the chemical composition of the battery, but the gas released by the maximum volume is hydrogen.
The fire temperature has reached more than 1,100 degrees.
Officials spoke on condition that they were not named because they had no right to speak publicly.
"Everything we find makes things worse and worse," an official said . ".
"We have been very lucky so far, but at some point it will end and it will be very difficult (explained) because everyone knows how dangerous the goods are.
A passenger plane may be able to withstand a fire caused by a small amount of lithium.
Ion batteries, according to a slide presentation by Airbus engineer Paul Rohrbach, but fire caused by many batteries may destroy the aircraft.
According to the company, the presentation reflects the views of other aircraft manufacturers and Airbus. U. S.
International officials have been slow to adopt security restrictions that could affect a strong battery-dependent industry. About 4.
8 billion lithium
Ion batteries were manufactured in 2013 and production is expected to reach 8 billion per year by 2025.
The battery contains two or more batteries.
Lithium batteries dominate the global battery industry because they are low-cost, lightweight and can hold more energy than other types of batteries.
The tests put airlines in trouble.
Shipment is permitted according to international safety standards.
They are also profitable.
So far, there has been no freight fire in passenger airlines due to lithium batteries.
But because some airlines ban shipments, this puts pressure on other airlines to follow suit or to be indifferent to safety risks.
Cargo airlines are continuing to transport the batteries, although they are believed to have caused or contributed to a fire that destroyed two Boeing 747 freighters in recent years, killing the pilots.
The pilot of the third freighter managed to escape after landing in Philadelphia, but the plane was also destroyed.
UPS recently completed a round of testing in a container that was adjusted to allow gas leakage while continuing to control the battery fire.
UPS spokesman Mike Mangeot said the company was encouraged by the results. U. S.
The hands of regulators are tied to Bill 2012 enacted by Congress in response to industry lobbying.
It prohibits the government from issuing regulations on battery shipments, which are stricter than those approved by the United States International Civil Aviation OrganizationN.
Unless the international investigation agency can prove that the battery ignited a fire that destroyed the plane.
This is difficult because of the fact that in the three cases so far suspected that the battery caused a fire, the aircraft was too damaged to determine the source of the fire.
