Those eggs you might have had for breakfast? They're not just food -- they may be the key to longer-running batteries in your devices. Scientists at MIT and Tsinghua University have developed a nanoparticle battery electrode whose egg-like design is built to last. Their invention, which houses a s...

Don't like that your Galaxy S6 conks out before you're finished for the day? Samsung might offer some relief in the future. Its scientists have developed lithium-ion battery technology that promises much longer-lasting power packs. They use a silicon anode (which promises much more capacity than a...

Sure, you can make solar-powered devices that store their excess energy in a battery, but what about the battery itself? Unfortunately, it's still behind the times -- the lithium-ion cells you see today have to be connected to another device to charge, and they're occasionally very dangerous than...

We've seen flexible displays for some time now, and engineers at Binghamton University developed an origami-inspired foldable battery. The folding part is great, but these batteries are also powered by bacteria and made from paper, providing an low-cost option for remote locales where resources ar...

Use a gadget with a lithium-ion battery inside and you'll eventually learn that these power packs decay once you've cycled them enough times. But have you ever wanted to see direct evidence of why they have a limited lifespan? The Department of Energy is happy to oblige. It developed a special...

Hate buying some new gadget, only to wind up with a sea of packing peanuts that do little more than spill on to the floor? Don't be too quick to toss them out -- they may be the key to a new generation of lithium-ion batteries. Purdue University researchers have developed a heating process that co...

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...

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...

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...

NASA knows that conventional battery power won't cut it at a certain point, especially when the agency's vehicles travel into deep space. To that end, it's asking both public institutions and companies to submit proposals for battery alternatives. The initiative will tackle both low-level energy c...
