The US Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL), industry and academia are teaming to give batteries from electric drive vehicles (EV) a “second life.” The NREL’s partner in the project is an industry-academia team led by the California Center for Sustainable Energy (CCSE). Possible secondary

Why do batteries lose their ability to hold a charge as they age? New research suggests the slow death of a battery might start at the nanoscale. Yann Guezennec and Giorgio Rizzoni of Ohio State University (OSU) developed new experimental facilities and procedures to charge and discharge commercially-available lithium-ion batteries

Could we one day see a battery-free future for mobile phones, electric cars and other devices? European researchers believe we can, and have just launched a €3.4 million project to develop a new material that could essentially allow phone housings and car bodies to act as their own power

Researchers at Stanford University have developed a way to turn an ordinary sheet of paper into an ultra-lightweight and flexible battery by dipping it into an ink made with carbon nanotubes and silver nanowires. The innovation offers a variety of promising uses, according to Yi Cui, an assistant professor of

A new type of battery being developed at the Massachusetts Institute of Technology (MIT) could eliminate the biggest barrier to renewable energy: the fact that the sun doesn’t always shine, the wind doesn’t always blow and the waves don’t always roll. An efficient, cost-effective and scalable battery

Today’s batteries are approaching the limits of their energy densities, which could mean a “power shortage” for users of increasingly small but energy-hungry gadgets, according to a study by NextGen Research. While a new generation of portable devices offer a wealth of features with increased demand for power, battery

Imagine no longer having to pop out to the shop for new batteries, but instead being able to print up a few on your home printer. If we’re not there yet, we’re certainly closer: researchers in Germany have developed a new battery that’s thinner than a millimeter,

Switzerland’s ReVolt Technology has made the Cleantech Summit 2009’s top 24 list of leading European startups and early-stage cleantech companies. ReVolt, which has developed a rechargeable zinc-air battery, was selected as one of the winners from a pool of more than 300 applicants. The top firms were recognised

The University of Glamorgan is collaborating with the Welsh firm Atraverda to develop a lighter, more powerful and more eco-friendly battery. The initiative was announced upon the university’s launch of the UK’s first Advanced Bi-Polar Battery Development research facility. Bi-polar batteries are widely regarded as having the best

A team of researchers from the US and Japan say a new type of battery — the “spin battery” — could lead to the development of more energy-efficient cars and computer hard drives with no moving parts. The battery would be charged with a magnetic tunnel junction, which applies a large magnetic

December’s proven to be a boon for cleantech geeks: earlier this month, we learned about the possibility of mobile devices powered by nothing but voice energy, and now comes news that engineers are working to build an energy-harvesting radio that never needs a battery change. Engineers at Kansas State

I try to use rechargeable batteries over disposable ones, but it sometimes seems I spend more time charging than using. So my ears perk up when I hear about a California cleantech company that claims to have developed a rechargeable battery with real oomph. San Diego-based PowerGenix says its new
