Hugh Pickens writes: "The Telegraph reports on the revolutionary 'STAIR' (St Andrews Air) battery could now pave the way for a new generation of electric cars, laptops and mobile phones. The cells are charged in a traditional way but as power is used an open mesh section of battery draws in oxygen from the surrounding air that reacts with a porous carbon component inside the battery, which creates more energy and helps to continually 'charge' the cell as it is being discharged. The battery has a greater storage capacity than other similar-sized cells and can emit power up to 10 times longer. "The key is to use oxygen in the air as a re-agent, rather than carry the necessary chemicals around inside the battery," says Professor Peter Bruce of the Chemistry Department at the University of St Andrews. "Our target is to get a five to ten fold increase in storage capacity, which is beyond the horizon of current lithium batteries.""
