The deep frying process isn't just useful for livening up your food -- it might also be the ticket to better batteries in your mobile devices. South Korean researchers have created highly conductive, stable electrode materials by spraying graphene oxide droplets into a very hot blend of acid and o...

Don't be too quick to toss out the battery from that ancient laptop -- it might just be the key to powering homes in developing countries, and helping the environment in the process. IBM researchers have revealed UrJar, a device that turns old lithium-ion battery packs into rechargeable energy sou...

Fast-charging batteries are all nice and good, but the lifespan matters, too -- why should you have to replace power packs (or entire devices) every couple of years ? You may not have to give up performance or longevity if researchers at Nanyang Technology University have their way. They've develo...

Forget lab-made materials like graphene -- natural, old-fashioned hemp may be the ticket to our energy future. Researchers have demonstrated that you can make very efficient carbon electrodes simply by heating hemp bast fibers in a two-stage process. The resulting substance holds as much energy as...

The lithium ion batteries in your mobile devices are inherently limited by the "ion" part of their name; they can safely use lithium only in the part of the cell that supplies ions, wasting a lot of potential energy. It's good news, then, that researchers at Stanford have developed a new lithium b...

Vanadium oxide seems to be the go-to guy in power storage right now. A new solid-oxide fuel cell -- developed at Harvard's School of Engineering and Applied Sciences -- that can also store energy like a battery, also uses the stuff. In the new cell, by adding a VOx layer it allows the SOFC to both...

Do you have to relieve yourself? Is your robot low on batteries? Your previously problematic world could soon be harmonized in one magical step. The Bristol Robotics Lab has been feeding funny trash to its Microbial Fuel Cells for quite some time -- rotten fruit, decomposed-in-sludge fly juice, gra...

Huzzah! Yet another discovery for us to add to our ever-expanding list of "awesome things that'll never actually happen!" Ibrahim Abou Hamad and colleagues from Mississippi State University have reportedly devised a method of charging batteries that could hasten the process rather significantly, and...
