Wood nanobattery could be green option for large-scale energy storage

By - July 6, 2013 3 Pictures
Li-ion batteries may be ok for your smartphone, but when it comes to large-scale energy storage, the priorities suddenly shift from compactness and cycling performance (at which Li-ion batteries excel) to low cost and environmental feasibility (in which Li-ion batteries still have much room for improvement). A new "wood battery" could allow the emerging sodium-ion battery technology to fit the bill as a long-lasting, efficient and environmentally friendly battery for large-scale energy storage. Read More

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.

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
