Researchers create flexible wires that could double as batteries

We literally live in a wired world, with wires snaking hither and yon transmitting electricity and data. Many are visible, while many more are hidden in the walls of buildings, the panels of cars, and the fuselage of aircraft. Now, imagine; what if we were able to turn each and every one of these into a battery that not only transmitted electricity but stored it too? Well, two researchers from the University of Central Florida (UCF) imagined that too, and came up with a way to use nano-technology to make wires with supercapacitance that may eventually also double as batteries.Read More

MIT finds new way to harvest energy from heat

Researchers at MIT and Stanford have found a new way to transform waste heat into electricity, particularly in situations where the temperature gradient is small, below 100º C (180° F). The technology uses widely available materials, and could be used to recycle the large amounts of wasted heat generated in industrial processes and electric power plants. Read More

Dual-functioning electrolyte improves capacity of long-life batteries

The three main components of a battery's makeup: the anode, cathode and the ion-conducting electrolyte, have been long understood to serve separate, independent functions. A team of researchers at the US Department of Energy's Oak Ridge National Laboratory (ORNL) is seeking to challenge this theory, experimenting with a dual functioning electrolyte that supplements the cathode to significantly improve the capacity and longevity of long-life batteries.Read More

Nanodot-based smartphone battery that recharges in 30 seconds

Today at Microsoft’s Think Next symposium in Tel Aviv, Israeli startup StoreDot has demonstrated the prototype of a nanodot-based smartphone battery it claims can fully charge in just under 30 seconds. With the company having plans for mass production, this technology could change the way we interact with portable electronics, and perhaps even help realize the dream of a fast-charging electric car.Read More

Review: Microsoft Surface Power Cover

Thinking about buying a hybrid PC that runs full Windows? Well, then battery life had better be on your radar, or you might end up with a device that conks out after just a few hours. If you own a Microsoft Surface, then that's becoming less of an issue. We've been testing a new accessory that can make a big difference in extending its uptimes. Read on, as Gizmag reviews the Surface Power Cover.Read More

Hybrid anode quadruples the lifespan of lithium-sulfur batteries

Increasing the range of electric vehicles and improving the storage of renewable energy systems are two examples of the benefits offered by lithium-sulfur batteries. Though they can hold four times the energy per mass of the lithium-ion batteries used today, their considerably shorter lifespan has proven something of a roadblock. Researchers from the Pacific Northwest National Laboratory (PNNL) have now designed a lithium-sulfur battery with four times the longevity, bringing the technology that little bit closer to maturity.

Pomegranate-inspired electrode could mean longer lithium-ion battery life

Though the use of silicon in lithium-ion batteries promises a whole new world of energy storage, it also poses several problems to a battery's durability and overall performance. A new electrode design inspired by clusters of pomegranate seeds and developed by researchers at the Department of Energy's National Accelerator Laboratory (SLAC) and Stanford University, overcomes some of these obstacles, bringing lighter and more powerful batteries closer to reality.
