Researchers at the University of Cambridge say they’ve created a lighter, cheaper, longer lithium-oxygen battery that could eventually rival gasoline engines in electric vehicles in terms of range and weight, Automotive News reported.

The scientists announced that they had created a working prototype of an “ultimate battery” that could be up to 10 times more energy-dense than lithium-ion batteries. They said the battery, to date, could be recharged more than 2,000 times.

The lithium-oxygen batteries could eventually replace lithium-ion batteries in electric vehicles and offer a range similar to gasoline engines, but researchers say that could be more than a decade away.   (Read More…)
