Scientists create lithium-ion batteries the size of a grain of sand

By - June 28, 2013 2 Pictures
While we’re currently witnessing the rise of tiny electronic devices such as biosensors, many of those devices do have one limiting factor – they still require not-so-tiny batteries, which ends up somewhat defeating the whole miniaturization process. Although some devices can get their power from external sources, scientists from Harvard University and the University of Illinois at Urbana-Champaign have come up with an alternative ... functional 3D-printed lithium-ion batteries no larger than a grain of sand.

New microbatteries combine the advantages of lithium-ion batteries and supercapacitors

By - May 8, 2013 5 Pictures
There can be little doubt that people love their mobile devices. But, by leaving them high and dry at the most inconvenient of times, this love generally doesn't extend to the batteries that power said devices. New microbatteries developed by researchers at the University of Illinois at Urbana-Champaign (UIUC) that measure just a few millimeters in size, yet are powerful enough to power a mobile phone may be more likely to inspire a little love.

Boosted Boards skateboard up for pre-order, still world's lightest EV

By - May 4, 2013 10 Pictures
Last year we reported on San Francisco-based startup Boosted Boards' eponymous debut product, an electric skateboard that can lay credible claim to being the world’s lightest electric vehicle. The skateboard was the subject of a successful Kickstarter campaign, and having survived the perils of moving from pitch to product, is now available for wider pre-order. Read More

Boeing completes final certification test of new 787 battery system

By - April 5, 2013 9 Pictures
On Friday, Boeing completed the final certification test required by the United States Federal Aviation Administration (FAA) for approval of the company’s lithium-ion battery modifications for the 787 Dreamliner aircraft. The test flight was made using a Boeing-owned production airplane built for LOT Polish Airlines with the company reporting that the test was “straightforward and the flight was uneventful.” Read More

Elon Musk: I can fix Boeing's battery problem

By - March 11, 2013 4 Pictures
Elon Musk says he's still waiting for a call from Boeing to fix the jumbo jet maker's overheating Dreamliner battery problem. For the past few months, Boeing's 787 fleet has been grounded in the United States following a lithium-ion battery that caught fire in flight. The National Transportation Safety Board was unable to determine the cause of the fire, but the Tesla and SpaceX CEO says the problem is clear to him, and he's willing to "do the fix" for Boeing.

Experimental lithium-ion battery can be stretched, twisted and wirelessly charged

By - February 27, 2013 3 Pictures
Thanks to the advent of stretchable electronics, we’re currently witnessing the development of things like smart fabrics, bendable displays, and even pressure-sensitive skin for robots. In many potential applications, however, the usefulness of such electronics would be limited if they still had to be hooked up to a rigid battery. In response to that problem, a team of scientists have recently created – you guessed it – a stretchable lithium-ion battery. Read More

Silicon nanoparticles used to create a super-performing battery

By - February 14, 2013 1 Picture
In some peoples’ opinion, electric cars won’t become truly viable until their batteries offer a lot more driving range, and can be recharged much more quickly than is currently possible. Well, those people may soon be getting their wish. Scientists at the University of Southern California have developed a new type of lithium-ion battery, that they claim holds three times as much energy as a conventional li-ion, and can be recharged in just ten minutes.

Plant root used to create eco-friendly lithium-ion battery

By - December 11, 2012 2 Pictures
Researchers have found an eco-friendly alternative to the metal ores currently favored in the electrodes of lithium-ion batteries. The new non-toxic and sustainable battery uses purpurin, a red/yellow dye extracted from the root of the madder plant that has been used for dying cloth for at least 3,500 years – meaning the substance can simply be grown rather than mined.

How to boost lithium battery performance – just add crushed silicon

By - November 6, 2012 2 Pictures
Researchers at Rice University and Lockheed Martin may have developed a low-cost method of creating longer-lasting, high-capacity lithium-ion batteries. Currently graphite is used as the anode in commercial li-ion products, despite the fact that a silicon anode could potentially store ten times more lithium ions. The team says it has solved one of the problems associated with silicon, which nearly triples the energy density of current li-ion batteries. Read More
