London, May 20 (ANI): British scientists have unveiled a revolutionary battery that runs on air.

By sucking in oxygen that reacts with carbon inside, the super-cell recharges itself.he invention will pave the way for a new generation of electric cars, inventors at Scotland's University of St Andrews said, reports The Sun.

The battery uses technology called stair - St Andrews Air - that lasts ten times longer than conventional ones and is also lighter and cheaper.

Mini versions could power laptops, mobile phones and iPods.

Chemistry professor Peter Bruce, who's leading the 1.5-million pound project to develop the battery, said: "The key is to use oxygen in the air as a re-agent, rather than carry the necessary chemicals around inside the battery.

"Our results so far have far exceeded our expectations." (ANI)
