A new type of dual-functioning electrolyte developed at ORNL could result in an improved c...

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

Researchers at Rice University have created an ultra-thin, high-performance flexible battery that is lithium-free, only a hundredth of an inch thick, and also doubles as a supercapacitor. The technology could find use in mobile and wearable electronics such as smartphones and fitness bands.  Read More

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

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.  Read More

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

Projected figures show the Gigafactory producing 500,000 units per year by 2020, with expe...

As Tesla’s Supercharger network expands and Model S sales continue to grow, so too does the company’s need to find a more economical battery solution. A proposed technology amalgamation in the form of the Gigafactory could theoretically reduce per kWh and lithium-ion costs by over 30 percent by 2020.  Read More

NanoFlowcell teases the Quant e-Sportlimousine

Lichtenstein-based start-up NanoFlowcell will reveal a working prototype it calls the Quant e-Sportlimousine at next week's Geneva Motor Show. More than just a concept car or styling exercise, the car showcases "an entirely new energy storage system."  Read More

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.  Read More

One of the new micro-batteries, amongst grains of rice for scale

In order to better understand and protect wild stocks of salmon, it's necessary to track their whereabouts using implanted acoustic tags. Needless to say, the longer that those tags are able to transmit a signal, the greater the amount of data that can be gathered. Scientists at Washington state's Pacific Northwest National Laboratory (PNNL) are helping make that happen, by developing batteries that have both a smaller size and higher energy density than conventional fish tag batteries.  Read More

The 'pomegranate' design reduces the surface area of the cluster to one tenth of the sum o...

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.  Read More
