A spinoff company from Arizona State University is planning to develop a metal-air battery which unlike lithium-ion batteries has an energy density 11 times greater, for less than one-third of the cost. Last week, the US Department of Energy awarded a $5.13-million research grant to Scottsdale, AZ-based Fluidic Energy. This company hopes that its ultra-dense energy storage technology will become reality.

Cody Friesen, the founder of Fluidic Energy and professor of materials science at Arizona State, along with other scientists have designed the new Metal-Air Ionic Liquid battery. “I’m not claiming we have it yet, but if we do succeed, it really does change the way we think about storage,” says Friesen, who was named one of Technology Review’s top innovators under 35 in 2009

So basically imagine a laptop battery that can last 11 times longer.....
