In collaboration with Vorbeck and researcher Ilhan Aksay at Princeton University, PNNL has demonstrated that small quantities of graphene — an ultra-thin sheet of carbon atoms — can dramatically improve the power and cycling stability of lithium-ion batteries, while maintaining high energy storage capacity. The pioneering work could lead to the development of batteries that store larger amounts of energy and recharge quickly.
Today, a typical cell phone battery takes between two and five hours to fully recharge. Researchers think using new battery materials with graphene could cut recharge time to less than 10 minutes.
Battelle, which operates PNNL for DOE, entered into a Cooperative Research and Development Agreement with Vorbeck for use of its unique graphene material, Vor-xTM, in battery materials synthesis research. Click here to read the announcement from Vorbeck.
This research is made possible the by the Department of Energy's Office of Energy Efficiency and Renewable Energy's Technology Commercialization Fund.
Vorbeck Materials Corp. (www.vorbeck.com) was established in 2006 to manufacture and develop applications using Vor-xTM, Vorbeck's patented graphene material developed at Princeton University. Vorbeck became the first company to successfully commercialize a graphene product in 2009 with the introduction of Vor-ink, a graphene-based conductive ink.
Pacific Northwest National Laboratory (www.pnl.gov) is a Department of Energy Office of Science national laboratory where interdisciplinary teams advance science and technology and deliver solutions to America's most intractable problems in energy, the environment and national security. PNNL employs 4,700 staff, has an annual budget of nearly $1.1 billion, and has been managed by Ohio-based Battelle since the lab's inception in 1965. Follow PNNL on Facebook, LinkedIn and Twitter.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
