Nanospheres were specifically created to protect the lithium from reacting chemically with...

Stanford University researchers claim to have created the first stable pure lithium anode in a working battery by using carbon nanospheres as a protective sheath to guard against degradation. As a result, the researchers predict that commercial developments may eventually result in anything up to a quadrupling of battery life in the not-too-distant future.  Read More

UC Riverside researchers have developed a lithium-ion battery with superior performance us...

Conventional lithium-ion batteries rely on anodes made of graphite, but it is widely believed that the performance of this material has reached its zenith, prompting researchers to look at possible replacements. Much of the focus has been on nanoscale silicon, but it remains difficult to produce in large quantities and usually degrades quickly. Researchers at the University of California, Riverside have overcome these problems by developing a lithium-ion battery anode using sand.  Read More

The TOSA buses charge as they stand at a bus stop

It’s one thing to invent an electric bus, a hydrogen car, or other green transportation technology, but quite another for it to work in the real world. For example, the Trolleybus Optimisation Système Alimentation (TOSA) flash-charging electric bus system may be the most brilliant idea ever, but if it can’t stay in the black, then might as well be drawn by diesel-powered horses. Scientists at the École Polytechnique Fédérale de Lausanne (EPFL) are hoping to avoid that scenario by developing a computer model that helps engineers integrate the buses into existing transport systems while keeping costs down.  Read More

The Zolo power and protection pack promises a battery backup, case, and cables for a low p...

Cases for smartphones are nothing new. Neither are backup batteries meant to keep phones juiced up when on the go. What is new, though, is ability to get a package that includes a case, battery backup, and cable for US$20. That's what Zolo is promising with its new accessory system.  Read More

The new technology could allow lithium-ion batteries to charge 16 times faster than presen...

Researchers at the University of California, Riverside have developed a silicon anode that would allow us to charge lithium-ion batteries up to 16 times faster than is currently possible. The new design relies on a three-dimensional, cone-shaped cluster of carbon nanotubes that could also result in batteries that hold about 60 percent more charge while being 40 percent lighter.  Read More

An electric car featuring Phinergy and Alcoa’s aluminum-air battery system made its track ...

Last year, Phinergy and Alcoa announced the development of an aluminum-air battery that could give an electric car a potential range of 1,000 miles (1,609 km), though stops for a water top-up would be needed every couple of hundred miles. Now the companies have debuted the technology on the track at Montreal’s Circuit Gilles-Villeneuve.  Read More

Caltech researchers are building nanoscale supermaterials from a CAD design (Photo: Meza/M...

Researchers at the California Institute of Technology are developing a disruptive manufacturing process that combines nanoscale effects and ad-hoc architectural design to build new supermaterials from the ground up. The materials can be designed to meet predetermined criteria such as weighing only a tiny fraction of their macroscopic counterpart, displaying extreme plasticity, or featuring outstanding mechanical strength.  Read More

Ford and Samsung are researching the possibility of a dual-battery system

Lithium-ion batteries are an industry standard for plug-in hybrid and electric vehicles, and Ford is convinced that they will be useful in cars without electric drive motors, too. The automaker is working with Samsung to research a dual-battery system that increases gas vehicle fuel economy.  Read More

Researchers have created wires with supercapacitance, which may eventually also double as ...

We literally live in a wired world, with wires snaking hither and yon transmitting electricity and data. Many are visible, while many more are hidden in the walls of buildings, the panels of cars, and the fuselage of aircraft. Now, imagine; what if we were able to turn each and every one of these into a battery that not only transmitted electricity but stored it too? Well, two researchers from the University of Central Florida (UCF) imagined that too, and came up with a way to use nano-technology to make wires with supercapacitance that may eventually also double as batteries.  Read More

The fiber-shaped Li-ion batteries can be woven into textiles capable of powering wearable ...

Scientists at the Fudan University in Shanghai, China, have developed a high-performance Li-ion battery made of carbon nanotube fiber yarns. Roughly one 1 mm in diameter, the fiber shaped lithium-ion batteries are reported lightweight enough to create weavable and wearable textile batteries that could power various devices. The researchers say that the yarn is capable of delivering nearly 71 mAh/g of power, and can also be woven into existing textiles to create novel electronic fabrics.  Read More
