World's first battery that charges on air.

• World's first battery fueled by air that could provide storage of energy 10 times as compared to those available today and can be used in electric cars, mobile phones and laptops.
• The revolutionary "STAIR" (St. Andrews Air) battery charged in a traditional way but as power is used or discharged, an open mesh section of the battery draws in oxygen from the surrounding air. This oxygen reacts with a porous carbon component inside the battery, which creates more energy and helps to continually charge for the cell as it is being discharged.
• This battery differs from the traditional battery using the chemical component lithium cobalt oxide, in as much as it uses porous carbon and oxygen drawn from the air and the cell is much lighter than current batteries.
• The cycle of air helps to recharge the battery as it is used. It has a greater storage capacity than other similar sized cells. It can emit power upto 10 times longer. The key is to use oxygen in the air as a reagent rather than carry the necessary chemicals around inside the battery.
• The battery is much smaller and lighter and hence better for transporting small applications. The size is also crucial for anyone trying to develop electric cars as they want to keep weight down as much as possible.
• In addition to being light it would be cheap as the porous carbon matrix which holds the Lithium battery ought to be economical.
