Technique developed to scale up production of graphene microsupercapacitors

February 20, 2013 8:34 am | News | Comments

While the demand for ever-smaller electronic devices has spurred the miniaturization of a variety of technologies, one area has lagged behind in this downsizing revolution: energy storage units, such as batteries and capacitors. Now, a team from University of California, Los Angeles may have changed the game by developing a groundbreaking technique that uses a DVD burner to fabricate microscale graphene-based supercapacitors.

Japan probe finds miswiring of Boeing 787 battery

February 20, 2013 6:49 am | by The Associated Press | News | Comments

A probe into the overheating of a lithium ion battery in an All Nippon Airways Boeing 787 found it was improperly wired, Japan's Transport Ministry said Wednesday. The Transport Safety Board said in a report that the battery of the aircraft's auxiliary power unit was incorrectly connected to the main battery that overheated, although a protective valve would have prevented power from the APU from doing damage.

NTSB: Plane batteries not necessarily unsafe

February 6, 2013 12:20 pm | by JOAN LOWY - Associated Press - Associated Press | News | Comments

The use of lithium ion batteries to power aircraft systems isn't necessarily unsafe despite a battery fire in one Boeing 787 Dreamliner and smoke in another, but manufacturers need to build in reliable safeguards, the nation's top aviation safety investigator said Wednesday.

Japan 787 probe finds thermal runaway in battery

February 5, 2013 2:37 am | by The Associated Press | News | Comments

Japan's Transport Safety Board says the lithium ion battery aboard a Boeing 787 flight in Japan last month found evidence of the same type of "thermal runaway" seen in a similar incident in Boston. The board said in a report Tuesday that CAT scans and other analysis found damage to all eight cells in the battery that overheated on an All Nippon Airways 787 on Jan. 16, prompting an emergency landing.

Self-powered nanoscale devices never need new batteries

February 4, 2013 8:59 am | by Adam Piore, Columbia University | News | Comments

Researchers at Columbia University are attempting to build self-powered systems using nanoscale devices that can transmit and receive wireless signals using so little power that their batteries never need replacing. Some of the chips built so far are 100 times more energy efficient than most standard technologies, and they rely on tiny bits of ambient solar energy to recharge themselves.

AP Exclusive: 787 grounded, but batteries can fly

February 3, 2013 4:34 am | by JOAN LOWY - Associated Press - Associated Press | News | Comments

At the time the government certified Boeing's 787 Dreamliners as safe, federal rules barred the type of batteries used to power the airliner's electrical systems from being carried as cargo on passenger planes because of the fire risk. Now the situation is reversed.

Japan to send investigators to US for 787 probe

January 31, 2013 10:55 pm | by The Associated Press | News | Comments

Japan's Civil Aviation Bureau is sending investigators looking into problems with Boeing 787 batteries to Seattle, where the aircraft are assembled. The Transport Ministry said members of the team working on the investigation would leave Tokyo on Sunday for Seattle. It provided no further details.

License will lead to faster-charging batteries

January 31, 2013 7:58 am | News | Comments

An enhanced battery technology that can potentially reduce the time it takes to charge cell phones, electric vehicles, and other battery-powered devices from hours to minutes is the subject of a commercial license agreement between Battelle and Vorbeck Materials Corp. The agreement will allow Vorbeck to bring lithium batteries incorporating Vor-X graphene technology to market for use in consumer portable electronic and medical devices, tools, and electric vehicles.

Exotic chemical compound could be useful in batteries

January 24, 2013 2:08 pm | News | Comments

Northwestern University graduate student Jonathan Barnes had a hunch for creating an exotic new chemical compound, and his idea that the force of love is stronger than hate proved correct. He and his colleagues are the first to permanently interlock two identical tetracationic rings that normally are repelled by each other. Many experts had said it couldn't be done.
