US Army's new portable charger brings power to soldiers in the field

By - May 27, 2013 3 Pictures
Portable electronic devices have revolutionized warfare, but they've also burdened the soldiers with an increasing number of batteries that adds significantly to their load. To help lighten the load, the US Army Research, Development and Engineering Command's communications-electronics center (CERDEC) has developed a military-grade Universal Battery Charger (UBC) to help soldiers in the field keep their electronics powered up.

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.

Sulfur-based polymers open door to a new class of battery

By - April 19, 2013 2 Pictures
Whether sulfur is a by-product or a waste product of oil refinement and coal combustion depends on how you slice it. Certainly, some of that sulfur can be put to use producing sulfuric acid, fertilizer and other chemicals, but much of it is accumulating into stockpiles that are expensive to maintain (due to the need to neutralize acidic run-off). Researchers at the University of Arizona think more of that sulfur could be put to use thanks to a new chemical process that uses sulfur to make plastics that may one day be used to make a new generation of lighter, more efficient lithium-sulfur batteries.

Phinergy's metal-air battery could eliminate EV range anxiety

By - April 3, 2013 3 Pictures
Israel-based company Phinergy claims to have developed metal-air battery technology that promises to end the range anxiety associated with electric vehicles. The company’s battery currently consists of 50 aluminum plates, each providing energy for around 20 miles (32 km) of driving. This adds up to a total potential range of 1,000 miles (1,609 km), with stops required only every couple of hundred miles to refill the system with water. 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.
