Flexible lithium-ion battery technology is on the march

By - August 10, 2012 1 Picture
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

Exovolt Plus stackable battery pack for mobile devices

By - August 9, 2012 4 Pictures
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

Iron-air batteries may prove a cheap, eco-friendly solution for energy storage

By - August 8, 2012 1 Picture
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

CryoSolplus could help keep EV batteries cool

By - July 13, 2012 1 Picture
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

Stanford scientists give new life to Thomas Edison's nickel-iron battery

By - July 8, 2012 6 Pictures
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

University of South Carolina researchers convert T-shirt into energy storage medium

By - July 4, 2012 8 Pictures
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.

Le Jamais Contente - the first purpose-built land speed record car

By - June 27, 2012 17 Pictures
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.

"Tin whiskers" could triple the capacity of lithium-ion batteries

By - June 11, 2012 2 Pictures
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

"Decorated" nanowires could lead to better batteries and solar cells

By - May 1, 2012 3 Pictures
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
