Batteries fuelled by air !!!!

Sounds like fiction huh?

The revolutionary STAIR (St Andrews Air) battery can recharge itself as it is being discharged. These batteries draw oxygen from the surrounding air onto an open mesh section of the battery. The oxygen reacts with a porous carbon component inside the battery which recharges this battery.

Unlike traditional batteries these batteries do not have any chemical constituent. It has only a porous carbon layer and makes use of atmospheric oxygen, so these cells are lighter. And since these cells are recharged as they are discharged they last longer and have greater storage.

These light and small sized batteries are expected to find their place in electric cars, laptops, mobile phones etc.
