Silicon Supercapacitor Built by Researchers

Silicon Supercapacitor Built by Researchers

Researchers at the Vanderbilt University in Nashville propose a novel silicon supercapacitor design. Such supercapacitor can be, theoretically, integrated into a silicon chip, opening some interesting options for energy storage. Batteries effectively store energy but do not deliver power efficiently because the charged carriers move slowly through the solid battery material. Capacitors, which store energy


WTF? Electric Cars without Batteries?

A technology Volvo is developing gives us some insight into the future of electric cars – while it’s easy to focus on their disadvantages today, new materials will bring much more advanced vehicles in the future. Since the battery is mainly what’s holding electric vehicles back – including trucks and buses – that’s what researchers are focused


$8 Million Battery Research Lab at University of Michigan Announced

A unique $8 million battery research lab at the University of Michigan will enable industry and university researchers to collaborate on developing cheaper and longer lasting energy storage devices in the heart of the U.S. auto industry. Initial support for the lab includes $5 million from the Michigan Economic Development Corporation (MEDC), $2.1 million from

Lithium Batteries: How Green Are They?

Electric cars have really taken off in the last two years or so and it’s understandably the case. Fossil fuelled autos may have become increasingly efficient in the last half decade or so, but in short they still fill the world with nasty exhaust emissions and in addition, they’re also eating up the world’s oil.


Table Salt: Making Solar Cells Better

Chemists at Oregon State University have identified a compound that could significantly reduce the cost and potentially enable the mass commercial production of silicon nanostructures—materials that have huge potential in everything from biomedicine to solar cells and energy storage. This extraordinary compound is called table salt. Simple sodium chloride, most frequently found in a salt


Need more proof that hybrid technology is the solid foundation for the future of automobiles? Following announcements from other luxury car brands like Ferrari and Porsche that they’re unveiling new electric models, Land Rover seems poised to have its hybrid Range Rover SUV on roads next year. The prototype cars have been doing well so


In Focus: Why Energy Storage is Cost Effective

California’s electricity system has reached a transforming regulatory milestone. On September 3, Commissioner Carla Peterman of the California Public Utilities Commission (CPUC) authored a proposed decision ordering a 1.325 GW utility energy storage procurement target for California’s electric grid by 2020, if viable and cost-effective. The CPUC is expected to decide on a final number


Innovation + Retrofitting = WINNING

Team UOW – from the University of Wollongong in Australia – took first place at the Solar Decathlon China!  Not only did their entry score the highest points in the competition but it received recognition as the oldest house in the event.  The Team avoided the environmental impacts of new construction by retrofitting a typical


The Largest European Energy Storage Project

The largest European energy storage experiment so far – involving a 6-megawatt (MW) lithium-ion battery – is under way in the UK. It’s a collaboration between utility S&C Electric Europe, high-tech firm Samsung SDI and energy management company Younicos that the three partners believe will save up to $9 million on upgrades, such as replacing


Solar Coffee is Buzzing

When two brothers Michael and David Hartkop had the idea to solar-roast coffee beans, they built a backyard concoction with an old satellite dish and broccoli strainer. Nine years later, the Hartkops are on their fifth-generation solar roaster and sell their USDA organic coffee to 60 wholesalers. Solar Roast Coffee was born in Oregon in


Tesla Introduces Battery Swapping

Just after Better Place went out of business because it couldn’t gain traction for its battery swapping technology, Tesla Motors has debuted a system that does the same thing. Tesla want to give people who buy its electric cars a choice – they can either swap the battery when it needs to be charged or hook up


Silicon-Boron Electrodes: The Key to Longer Battery Life?

The electrode material has a decisive influence on a battery’s capacity. So far, the negative electrode typically consists of graphite, whose layers can store lithium atoms. While silicone could be much more efficient choice, most silicon-based designs have a major flaw—structures tend to crack or break easily when they are used repeatedly. Scientists at the


Stanford Scientists Create Low-Cost Zinc-Air Battery

A new zinc-air battery developed by the Stanford scientists could prove to be a low-cost to lithium-ion technology. This battery has higher catalytic activity and durability than similar batteries made with platinum and other costly catalysts. The results of the study were published in the journal Nature Communications. “There have been increasing demands for high-performance,
