A study by IBM researchers has revealed that many discarded laptop batteries have the potential to provide enough power to keep the lights running in homes in poorer countries around the world. The India-based team conducted a small study to test the viability of the idea, with work now focused on streamlining a prototype system.  Read More

As modern power generation methods are designed to squeeze the most power from the least amount of fuel, engineers are constantly looking at techniques to improve efficiency. One way to achieve this is to scavenge waste energy left over from the production process to capture and convert low-grade heat into usable energy. In pursuit of this goal, engineers at Pennsylvania State University have produced an ammonia-based battery that not only captures and converts waste heat economically and efficiently, but is claimed to do so at a greater capacity than other similar systems.  Read More

Researchers at Drexel University have hit upon a conductive clay which they claim is an "exceptionally viable candidate" to one day replace the electrode materials used in batteries and supercapacitors. Sure, another day another super material, but MXene, as it's called, does boast some rather intriguing properties.  Read More

There's another promising contender in the race to supplant the dominance of lithium-ion and metal-hydride based batteries in the world of energy storage. New research from the Karlsruhe Institute of Technology's (KIT's) Helmholtz Institute Ulm (HIU) details the development of an electrolyte that can be used in new magnesium-sulfur battery cells that would be more efficient and inexpensive than the dominant types of batteries in use today.  Read More

The Xoo Belt is charged via a microUSB port contained within the buckle

Nifty, a British company which successfully crowdfunded the MiniDrive, is back with a new product. The Xoo Belt is a belt which hides flexible batteries capable of charging your smartphone on the go. Thankfully, as you would expect from a belt, it also holds your trousers up.  Read More

After its historic landing on a comet, the Philae spacecraft has gone silent. Trapped on its side in a shadowed hole, the unmanned European Space Agency lander was unable to receive enough sunlight to recharge its battery and contact was lost today at 00:36 GMT when power levels dropped below critical.  Read More

During Wednesday’s historic landing on comet 67P/Churyumov-Gerasimenko, the European Space Agency's Philae lander suffered a setback that may cut its mission short. Due to equipment malfunctions, the unmanned, washing machine-sized lander failed to secure itself to the surface of the comet. In the 1/100,000 gravity, Philae bounced back into space twice, eventually landing in a hole about a kilometer (0.6 mi) from its designated landing area, where its batteries may not be able to charge properly.  Read More

A top view of the nanopores, each of which is a separate battery in its own right

As electronic devices continue to get smaller, one question becomes increasingly pertinent – how will we power them? Well, smaller batteries would seem to be the most obvious answer. With that in mind, researchers at the University of Maryland have succeeded in creating a tiny battery that incorporates even smaller structures, known as nanopores.  Read More

QUT sees cars powered by their body panels a reality within five years (Photo: Shutterstoc...

Imagine opening up an electric car and finding no batteries. An absent-minded factory worker or magic? Perhaps neither. If nanotechnology scientists led by the Queensland University of Technology (QUT) are on the right track, it may one day be a reality as cars are powered not by batteries, but their body panels – inside which are sandwiched a new breed of supercapacitors.  Read More

It can be a herculean task to get kids to eat their vegetables, but they'll happily chow down on things they aren't supposed to. If one of those things is a button battery, serious injuries can result in the form of burns to the esophagus or tears in the digestive tract. Researchers may not have found a way to stop kids swallowing button batteries, but they have found a way to make such culinary no-nos safer.  Read More
