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

Manned electric-powered aircraft have made record-breaking flights and turned more than a few heads in the past few years, and it's not a trend that's likely to slow down. Last week, the E-Fan electric trainer airplane developed by the Airbus Group made its first public flight before a collection of French dignitaries. Currently a demonstrator for electric aircraft technology, Airbus says that is will be used as the basis for building a new pair of electric training aircraft models.  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

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

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

Designed for transporting light cargo, the Kombi EV has a range of 50 miles (80.5 km) on a...

US-based Cenntro Motors has announced plans to launch its Kombi EV in the second quarter of 2014. The all-electric utility vehicle has a claimed top speed of 31 mph, a range of 50 miles and is said to achieve fuel economy of more than 240 MPGe.  Read More

The Boeing 787 Dreamliner aircraft initially suffered from problems with its lithium-ion b...

Last year, lithium-ion battery fires became a hot topic, pardon the inescapable pun, with both a Tesla automobile and the Boeing 787 Dreamliner succumbing to fires. In cross-disciplinary research at the University of North Carolina (UNC), a compound being studied to prevent marine life from sticking to ships may also be the solvent (and the solution) to keep lithium ion batteries from catching alight when they overheat.  Read More
