Scientists use Silly Putty ingredient to improve batteries

If you see a group of scientists playing with a blob of Silly Putty, they might not be goofing off, they may be working on a technological breakthrough. That turned out to be the case with researchers at the University of California, Riverside Bourns College of Engineering , who have developed a way to use an ingredient in Silly Putty to improve lithium-ion battery life between charges by three times the industry standard.Read More

E-Fan electric aircraft makes first public flight

Manned electric-powered aircraft have made record-breaking flights and turned more than a few heads in the past few years, and it's not a trend that's likely to slow down. Last week, the E-Fan electric trainer airplane developed by the Airbus Group made its first public flight before a collection of French dignitaries. Currently a demonstrator for electric aircraft technology, Airbus says that is will be used as the basis for building a new pair of electric training aircraft models.Read More

Hybrid anode quadruples the lifespan of lithium-sulfur batteries

Increasing the range of electric vehicles and improving the storage of renewable energy systems are two examples of the benefits offered by lithium-sulfur batteries. Though they can hold four times the energy per mass of the lithium-ion batteries used today, their considerably shorter lifespan has proven something of a roadblock. Researchers from the Pacific Northwest National Laboratory (PNNL) have now designed a lithium-sulfur battery with four times the longevity, bringing the technology that little bit closer to maturity.

Pomegranate-inspired electrode could mean longer lithium-ion battery life

Though the use of silicon in lithium-ion batteries promises a whole new world of energy storage, it also poses several problems to a battery's durability and overall performance. A new electrode design inspired by clusters of pomegranate seeds and developed by researchers at the Department of Energy's National Accelerator Laboratory (SLAC) and Stanford University, overcomes some of these obstacles, bringing lighter and more powerful batteries closer to reality.

New electrolyte could mean an end to spontaneously combusting lithium batteries

Last year, lithium-ion battery fires became a hot topic, pardon the inescapable pun, with both a Tesla automobile and the Boeing 787 Dreamliner succumbing to fires. In cross-disciplinary research at the University of North Carolina (UNC), a compound being studied to prevent marine life from sticking to ships may also be the solvent (and the solution) to keep lithium ion batteries from catching alight when they overheat.

Urb-E squeezes onto personal mobility train

Compact personal mobility vehicles are a great option for commuters looking to solve the "last mile" problem. The latest such vehicle to hit the streets aimed at filling this need is the Urb-E from Urban Mobility, which claims it is the "world's most compact electric vehicle."Read More
