Hybrid ribbons a gift for powerful batteries

March 25, 2013 12:21 pm | by Mike Williams, Rice University | News | Comments

According to recent research at Rice University, vanadium oxide and graphene may be a key new set of materials for improving lithium-ion storage. Ribbons created at Rice from these two materials are thousands of times thinner than a sheet of paper, yet have potential that far outweighs current materials for their ability to charge and discharge very quickly. Initial capacity remains at 90% or more after more than 1,000 cycles.

Investigators scold Boeing over 787 comments

March 22, 2013 1:37 pm | by JOSHUA FREED - AP Business Writer - Associated Press | News | Comments

Boeing's comments about the smoldering batteries on its 787 have annoyed the National Transportation Safety Board. Boeing gave its own account of two battery incidents, which included a fire, at a detailed press briefing in Tokyo last week. The problem is that the NTSB is still investigating the incidents. Boeing is a party to the investigation, meaning it provides technical experts and, in effect, gets a seat at the table as investigators try to sort out what happened.

Boeing reports 787 battery fix to Japan regulators

Clever battery completes stretchable electronics package

February 27, 2013 8:05 am | News | Comments

Northwestern University’s Yonggang Huang and the University of Illinois’ John A. Rogers are the first to demonstrate a stretchable lithium-ion battery—a flexible device capable of powering their innovative stretchable electronics. Their battery continues to work—powering a commercial light-emitting diode (LED)—even when stretched, folded, twisted and mounted on a human elbow. The battery can work for eight to nine hours before it needs recharging, which can be done wirelessly.

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.

A new cheap, strong lithium-ion battery

February 12, 2013 11:18 am | News | Comments

Researchers at the University of Southern California have developed a new lithium-ion battery design that uses porous silicon nanoparticles in place of the traditional graphite anodes to provide superior performance. The new batteries hold three times as much energy as comparable graphite-based designs and recharge within 10 minutes.

U.N. agency moves to kill aircraft battery exemption

February 12, 2013 11:08 am | by JOAN LOWY - Associated Press - Associated Press | News | Comments

A U.N. agency that sets global aviation safety standards is moving to prevent aircraft batteries like the one that caught fire on a Boeing 787 last month from being shipped as cargo on passenger planes, people familiar with the effort said.

New initiative to improve lithium-ion batteries

February 12, 2013 10:23 am | News | Comments

A Lawrence Livermore National Laboratory team is working to improve lithium-ion battery performance, lifetime, and safety. Working with Lawrence Berkeley National Laboratory, the scientists are developing a new methodology for performing first-principles quantum molecular dynamics simulations at an unprecedented scale to understand key aspects of the chemistry and dynamics in lithium-ion batteries, particularly at interfaces.

US: 787 battery approval should be reconsidered

February 7, 2013 7:15 pm | by JOAN LOWY - Associated Press - Associated Press | News | Comments

The U.S. government should reassess its safety approval of the Boeing 787's lithium ion batteries, America's top accident investigator said Thursday, casting doubt on whether the airliner's troubles can be remedied quickly.

Netzsch, NREL announce partnership

February 7, 2013 11:29 am | News | Comments

Netzsch Instrument North America LLC and the National Renewable Energy Laboratory have announced a joint collaboration to develop an instrument designed to test the performance and safety of large-format lithium-ion batteries (LFLIB). The instrumentation will be able to safely and accurately characterize heat output and efficiency of LFLIB, in varying temperature, pressure, load, and use conditions.

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.

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.

What holds energy tech back? The infernal battery

January 23, 2013 10:10 am | by Seth Borenstein, AP Science Writer | News | Comments

As 21st century technology strains to become ever faster, cleaner and cheaper, an invention from more than 200 years ago keeps holding it back. It's why electric cars aren't clogging the roads and why Boeing's new ultra-efficient 787 Dreamliners aren't flying high. And chances are you have this little invention next to you right now and probably have cursed it recently: the infernal battery.
