Salt has long been used to preserve meat, and now researchers at Cornell University have found that adding certain salts to the anodes of lithium-based batteries can also increase their useful life by a very large factor, solving long-standing problems associated with cell degradation. The advance can be adapted to other metal-based chemistries, including the lighter and more energy dense lithium-sulfur cells and, according to the researchers, might see commercial applications in as little as three years.  Read More

The PowerTrekk 2.0 is designed to charge more power-hungry gadgets such as tablets

After introducing its PowerTrekk portable fuel cell charger several years ago, Swedish company myFC is readying the 2.0 version. The new model is close to three times more powerful than the original, offering enough juice to charge tablets, along with smaller devices like smartphones and GPS units.  Read More

Batteries for EVs like this Tesla Model S could be getting cheaper and more plentiful, onc...

If electric vehicles are to ultimately become as popular as Tesla hopes they will, then a whole lot of cost-effective batteries are going to be needed. That's why earlier this year, the automaker proposed a "Gigafactory" where it could crank out huge quantities of batteries. By making so many, it could drive down the price per battery via economy of scale. Yesterday, the company announced that it and Panasonic had signed an agreement to build that factory.  Read More

UC Riverside researchers have developed a lithium-ion battery with superior performance us...

Conventional lithium-ion batteries rely on anodes made of graphite, but it is widely believed that the performance of this material has reached its zenith, prompting researchers to look at possible replacements. Much of the focus has been on nanoscale silicon, but it remains difficult to produce in large quantities and usually degrades quickly. Researchers at the University of California, Riverside have overcome these problems by developing a lithium-ion battery anode using sand.  Read More

The new technology could allow lithium-ion batteries to charge 16 times faster than presen...

Researchers at the University of California, Riverside have developed a silicon anode that would allow us to charge lithium-ion batteries up to 16 times faster than is currently possible. The new design relies on a three-dimensional, cone-shaped cluster of carbon nanotubes that could also result in batteries that hold about 60 percent more charge while being 40 percent lighter.  Read More

Ford and Samsung are researching the possibility of a dual-battery system

Lithium-ion batteries are an industry standard for plug-in hybrid and electric vehicles, and Ford is convinced that they will be useful in cars without electric drive motors, too. The automaker is working with Samsung to research a dual-battery system that increases gas vehicle fuel economy.  Read More

The fiber-shaped Li-ion batteries can be woven into textiles capable of powering wearable ...

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 allow energy to be stored directly in structural material...

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.  Read More

Marbel uses a lithium-ion battery and a Kevlar and carbon fiber composite deck to keep its...

Electric skateboards are certainly building up some momentum as a form of urban transport, and they seem to just keep getting lighter and lighter. Florida-based start-up Marbel is the latest to set its wheels in motion, this week launching a crowdfunding campaign for what it claims to be the world's lightest electric vehicle – the 9.9 lb Marbel.  Read More

Silicon polymer and battery used for the research

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.  Read More
