A newly developed bendable thin-film lithium-ion battery could help bridge the gap to high...

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a promising solid state, thin-film lithium-ion battery that claims the highest energy density ever achieved for a flexible battery. The new design, which showed for the first time that high-performance thin films can be used for flexible batteries, may be commercialized as early as next year.  Read More

Exogear claims its Exovolt Plus is the world's first stackable battery pack for mobile dev...

If the idea of your mobile gadget running out of juice leaving you incommunicado (or, heaven forbid, bored) fills you with fear, then a battery pack is the obvious solution. But what if your power needs vary from day to day? Exogear has developed a battery pack that it touts as the world’s first stackable battery pack that is designed to adapt to suit your battery needs, no matter how small or how great.  Read More

Revamping a concept that was first explored forty years ago, researchers at the University of Southern California (USC) are putting the final touches on a patent-pending design for cheap, rechargeable, high energy density iron-air batteries. Because of their unique features, the batteries look particularly well-suited to the kind of large-scale energy storage that could accelerate the adoption of renewable energy sources.  Read More

Drexel University research combining the best features of batteries and supercapacitors co...

Researchers at Drexel University are developing an electrochemical flow capacitor (EFC) that combines the storage capabilities of batteries with the much longer cycle life and power output of supercapacitors. The team's goal is to improve the stability of the energy grid and ease the integration of renewable energy sources.  Read More

A sample of Fraunhofer's CryoSolplus phase-change battery coolant

One of the big enemies of electric vehicle batteries is heat. Batteries already warm up under normal use, but when hot summer temperatures or high workloads are thrown in, overheating becomes a real possibility. According to the Fraunhofer Institute for Environmental, Safety and Energy Technology, running a battery at ten degrees over its maximum “comfort level” of about 35ºC (95ºF) can deplete its service life by half. That’s why researchers there have developed a battery coolant known as CryoSolplus, which is said to offer three times the cooling capacity of plain water.  Read More

A green, rechargeable battery that is suitable for powering electric vehicles and stationary power storage applications, and that would survive tens of thousands of charge cycles in a useful life of 100 years without loss of capacity. What could be a better innovation for our times? Such a battery has been developed, and recently improved by Stanford researchers. Oh, one other thing. The battery was invented by Thomas Edison in 1901.  Read More

The researchers used a standard T-shirt purchased from a local discount store for their wo...

As manufacturers of smartphones and mobile devices strive to make their products increasingly portable, they repeatedly come up against the constraints of existing battery technology. However, Xiaodong Li, a professor at the University of South Carolina (USC) believes that we will soon be able to employ the clothes we wear to help overcome such challenges and to this end, Li has transformed T-shirt material into an energy storage medium which could one day be used to power portable devices.  Read More

La Jamais Contente

Despite the coming of the electric vehicle during the last decade, there were far more electric vehicle manufacturers in the world 100 years ago than there are today. Hundreds of manufacturers, a large proportion of them electric, competed in the fledgling automotive marketplace. This competition drove these manufacturers to seek new and novel ways to seek publicity, and when a French Automobile magazine ran top speed trials in December 1898, it sparked a flurry of record attempts and six land speed records in just four months. The electric Jamais Contente, which was the first purpose-built speed record attempt car, prevailed in this early tussle by raising the land speed record to 105.878 km/h (65.79 mph) in April 1899.  Read More

Tin anode creator Prof. Grant Norton and student, David Mackay

For over 60 years, electrical engineers have been trying to minimize the problem of tin whiskers. Growing on tin-plated electronics, the needle-like structures get up to ten millimeters long, and can cause short circuits. Instead of trying to eliminate them, however, Washington State University’s Prof. Grant Norton has been looking into ways of growing them – albeit in a controlled manner. His research has led to the creation of a tin battery anode, which he claims could triple the capacity of lithium-ion batteries.  Read More

A nanowire sporting tendrils of nanoparticles, which greatly add to its surface area

Higher-density batteries, more efficient thin-film solar cells, and better catalysts may all soon be possible, thanks to a new technique that allows nanowires to be “decorated” with nanoparticles. Using the novel technology, scientists from Stanford University have been able to festoon the outside surfaces of nanowires with intricate chains of metal oxide or noble metal nanoparticles, thereby drastically boosting the effective surface area of the nanowires. Other researchers have previously tried to achieve the same end result, but apparently never with such success.  Read More
