Boeing 787's lithium batteries deepen safety concerns - lithium ion batteries for sale

Lithium batteries capable of leaking corrosive liquids and triggering fires have become the main safety issue for Boeing's 787 Dreamliner, which is clearly much more serious than government or company officials admitted less than a week ago. The U. S.
Later on Wednesday, the Federal Aviation Administration suspended Boeing's latest, state-of-the-art aircraft until the risk of a battery fire was resolved.
The order applies only to six Dreamliners operated by United AirlinesS.
Carrier of 787 s
But airlines and civil aviation departments in other countries have followed suit quickly.
Japan's two largest airlines on Wednesday voluntarily suspended 787 flights before the FAA ordered them, after one of the aircraft landed in Japan on an emergency basis.
On Thursday, the European Aviation Safety Agency ordered all European airlines to stop the plane.
The Indian government has ordered Air India to fly six Boeing 787 aircraft, while Air Ethiopia has suspended four Boeing 787 aircraft for preventive inspections.

However, Air Canada's David Telman said Air Canada had time to resolve the 787 issue before Boeing began delivering its first aircraft.
"If we had this conversation in six months, I would start to worry, so there is a lot of time to deal with the initial pain," he said in an interview . ".

Transport Minister Ray LaHood reiterated to reporters that he believed the plane was safe and that he would not hesitate to fly it.
LaHood and FAA Administrator Michael Huerta made it clear at a press conference last week that the aircraft was safe, although they ordered a safety review of the aircraft.
However, with the details of the two battery failures 10 days apart surfaced, it is clear that the FAA was unable to wait for the safety review to be completed before taking action.
An all-day air carrier 787 inspection of an emergency landing in western Japan found that flammable battery fluid electrolyte leaked from the aircraft's main lithiumion battery.
Investigators found burn marks at the damage.
Japan's Kyodo news agency quoted koyo Kosugi, an investigator from Japan's Ministry of Transport, as saying that liquid leaked through the floor of the electrical room outside the plane.
In the first battery accident in January
7. It took firefighters 40 minutes to put out a fire centered on Japan Airlines's 787 auxiliary power unit.
Shortly after the plane landed at Boston Logan International Airport, there were no passengers left.
The FAA confirmed that the two incidents resulted in the release of flammable electrolyte, thermal damage and smoke.
Safety experts say the release of battery fluid is particularly worrying.
This fluid is highly corrosive, which means it can quickly damage wires and components.
787 relies more on electronic equipment than on hydraulic or mechanical systems than any other passenger aircraft in operation.
The electrolyte fluid also conducts electricity, so when it spreads it will short-circuit, interfere with electrical signals, making it impossible for the pilot to control the plane and ignite the fire.
Its corrosiveness has raised concerns about whether a leak would weaken the critical support structure of the aircraft, safety experts say, although 787 is the first passenger plane made primarily of lightweight composites, but this material is less vulnerable to corrosion than aluminum.
"This is a very serious situation whenever your battery fluid leaks," said Kevin Hiatt, president and CEO of the Virginia Alexander Flight Safety Foundation, which promotes global aviation safety.
A liquid leak found on a Japanese airline plane is a "very important discovery," said John gorlia, an aircraft maintenance specialist and former American airline. S.

Jim McNerney, chairman, president and CEO of Boeing, said the company is working with the FAA to resolve the issue as soon as possible.
"We believe 787 is safe and we support its overall integrity," he said in a statement . ".
"In the next few days, we will take all necessary measures to ensure the safety of 78 7 to our customers and the travel public and to have the aircraft return to service.
"Mike Sinatra, chief engineer of the 787 aircraft, said last week that the aircraft's battery had been running through a combination of 1.

The aircraft were built with a variety of protective measures to ensure that the failure did not endanger the aircraft, he said. "The lithium-
The ion selection design is because it is the only battery that can be charged in a short period of time.
Rechargeable lithium batteries are widely used in consumer electronics such as laptops and mobile phones.
But they are also considered short-lived.
Circuit and start fire, these fires are very hot and difficult to put out.
The transportation of lithium batteries is suspected of causing the severity of the fire that has caused the crash of two cargo planes since 2010.
Sinatra said Boeing had long been aware of possible problems with lithium batteries.
However, he said that the aircraft designed by Boeing has special safety precautions to prevent possible battery fires and to keep the fire under control in a small area in the event of a fire.
Whether it's GS Yuasa
Nor Thales, a Japanese company that provides batteries for 787, will comment on recent issues, which produce a battery charging system.
To solve this problem, Boeing and its customers need to act quickly.
The aircraft manufacturer has booked orders for more than 800 aircraft from airlines around the world, which are attracted by improved fuel efficiency.
