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.

Scientists create weavable Li-ion fiber battery yarn

Scientists at the Fudan University in Shanghai, China, have developed a high-performance Li-ion battery made of carbon nanotube fiber yarns. Roughly one 1 mm in diameter, the fiber shaped lithium-ion batteries are reported lightweight enough to create weavable and wearable textile batteries that could power various devices. The researchers say that the yarn is capable of delivering nearly 71 mAh/g of power, and can also be woven into existing textiles to create novel electronic fabrics. Read More

Structural supercapacitors could make batteries and power cords obsolete

Imagine using a mobile phone powered entirely by its casing, or an electric car that runs off power stored in its chassis. Researchers at Vanderbilt University have created a structural supercapacitor that could, they believe, bring this closer to reality, making batteries and power cords obsolete. The structural supercapacitor could make it possible to store energy directly in structural materials, allowing them to deliver power long-term while surviving the real-life mechanical stresses they're bound to experience.

Scientists use Silly Putty ingredient to improve batteries

If you see a group of scientists playing with a blob of Silly Putty, they might not be goofing off, they may be working on a technological breakthrough. That turned out to be the case with researchers at the University of California, Riverside Bourns College of Engineering , who have developed a way to use an ingredient in Silly Putty to improve lithium-ion battery life between charges by three times the industry standard.

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.

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.

Panasonic's Power Supply Container: A solar power plant in a box

In an effort to bring reliable electricity supplies to emerging regions and remote island communities, Panasonic has developed an expandable, portable, self-contained photovoltaic system. The "Power Supply Container" comes equipped with 12 of Panasonic's HIT240 solar modules on the roof and generates approximately 3 kW of electricity, with 24 lead-acid batteries capable of storing 17.2 kWh of energy used to store excess electricity.

The story of the RYNO electric microcycle – in the inventor's own words

Six years ago, Chris Hoffmann's 13-year-old daughter Lauren said, “Daddy, I’ve been thinking about this one-wheeled motorcycle I saw in a video game. Could you actually build something like that?” What happened next changed his life. In the next few months, Chris' new company begins shipping the Ryno, a self-balancing, one-wheeled US$5250 personal mobility device that has caused tidal waves of interest across the globe. This is Chris Hoffmann’s story of what happened in the intervening six years, in his own words, and that's 20-year-old Lauren with daddy's one-wheeled motorcycle. Read More
