lithium battery industry sees safe technology for planes

Lithium-
It\'s like two Boeing batteries are overheating.
According to experts speaking at a forum today, the 787 Dreamliner can even be safely used for the most critical traffic use.
\"The safety of this technology is increasing year by year,\" said Dan mehhty of Battery Safety Consulting.
In Albuquerque, New Mexico.
Vince sticky, senior vice president of strategy and business development at Quallion LLC, said in an interview that the question is whether safeguards are too expensive, such as extensive testing and construction in protection circuits. Los Angeles-
Quallion produces batteries for space and medical equipment.
He and Doherty spoke today in the United States. S.
The National Transportation Security Council forum in Washington.
Boeing has proposed a number of protective measures, including some of the viscous protection measures described in the redesigned battery, including titanium vents, which can discharge smoke and smoke outside if the fire starts,The U. S.
The Federal Aviation Administration has yet to announce when it will take action on Boeing\'s proposed fix.
As part of the January 7 87 battery fire investigation, the safety committee.
Hold today\'s forum in Boston to hear from academics, industry and government officials about how to make cells safer.
It will have a separate hearing on April 23.
Check the battery design of the Dreamliner and how it is certified by the FAA.
Rechargeable lithium battery to power Apple\'s devices
In his opening speech, NTSB Chairman Debbie Hersman said that iPad to electric tools are increasingly being used to transport equipment because they are lighter and more powerful than other battery technologies. “Yet, lithium-
Like other power sources, ion batteries, such as gasoline that powers so many individual vehicles, can also pose risks, \"Hersman said.
\"These batteries are designed to generate energy ---
It is their nature that poses the greatest risk.
In an interview, Visco declined to say whether Boeing\'s plan was enough to secure the aircraft.
The introduction of new protection measures would bring the 78 7 battery pack designed almost a decade ago to a more current standard, he said.
The aircraft, the latest by Boeing, has been grounded since January.
16. after two incidents of smoke in the lithium battery pack.
When they were on fire, lithium
The battery can burn violently, spewing flammable gas and molten metal.
However, in recent years, in use, including hybrid buses and power grids, the battery is much larger than the 787 battery.
Jiang Ming, a professor at MIT, also spoke at today\'s forum.
The industry is becoming more aware of the way battery failures occur, including internal short circuit
Jiang said circuit, overheating, manufacturing defects and damage during use.
\"All major manufacturers are trying to test and plan these failure patterns,\" he said in an interview . \".
Lithium used by NASA
Battery Safety agency head Judith jevarayan said that since 1999, each battery has been extensively tested based on a manned space mission, and measures have been taken to limit fire
Other steps, such as never fully charging the battery, limit the heat released when the battery fails, she said.
\"There\'s no reason to say lithium-
Ions don\'t have a place in high school.
Consequences applications, such as passenger planes, \"said Ahmed HTY, head of battery testing at Sandia National Laboratory.
One of the topics discussed at the hearing may reappear in NTSB\'s investigation: a test of the type of fault that occurred in Boston, and NTSB found that it was an internal short circuitcircuit.
There is currently no agreement on how best to test the internal short circuit of the battery, Laurie Florence, chief engineer of ul llc, the test organization formerly known as Underwriters Lab.
Said at the forum.
To secure the 787 battery, Boeing pierced a battery with a nail and simulated a short batterycircuit.
The battery was not on fire during Boeing\'s test.
Florence says the nail test does not accurately replicate a short paragraph.
Since 2009, the FAA has recorded 33 cases of batteries in which passengers caught fire on commercial aircraft or cargo.
Of these cases, 26, or 79%, involved lithium
Battery-based, according to the agency.
According to the safety committee, since 2006, three cargo planes have been destroyed in a fire in the presence of lithium batteries.
These cells are being transported, not part of the plane.

New regulations have been implemented for air transportation of lithium batteries.

The NTSB-Based Rechargeable Battery Association trade group said.
The airline told the FAA that on some cargo flights, up to 85% of the cargo is dangerous due to lithium batteries, said Janet McLoughlin, deputy director of the agency\'s hazardous materials program. Boeing got U. S.
Regulatory Authority permission to install lithium
In 2007, three years after passenger airlines were banned from carrying non-batteries, ion batteries on Dreamliner
As the rechargeable type of goods. GS Yuasa Corp.
A battery pack of 787 has been made in Kyoto, Japan.
The company sold them to Thales SA and then supplied them to Boeing.
787 is the first passenger plane designed with lithium.
Ion batteries as part of the electrical system.
When the engine is not running on the ground, one starts the auxiliary generator and the other powers the equipment, such as the electric brake of the aircraft.
Smaller lithium
According to Boeing, ion pack also provides backup power for cockpit displays.
Boeing chose them for the 787, it uses more power than the previous design, because they are lighter and have more energy to charge quickly, 787 Mike Sinatra, chief project engineer, said in a briefing on January.
