Air-fuelled Battery Could Last 10 Times Longer

May 25th, 2009 | No Comments | Posted in Batteries

Researchers at the University of St Andrews are working on a new type of air-fuelled battery, that could give up to ten times the energy storage of current designs. This step-change in capacity could pave the way for a new generation of electric cars, mobile phones and laptops.

The research work, funded by the Engineering and Physical Sciences Research Council (EPSRC), is being led by researchers at the University of St Andrews with partners at Strathclyde and Newcastle.

The cells of the STAIR battery (St Andrews Air) are charged in a traditional way but as power is used an open mesh section of the battery draws in oxygen, which reacts with a porous carbon component inside the battery to create more energy.

The new design has the potential to improve the performance of portable electronic products and give a major boost to the renewable energy industry. The batteries would enable a constant output from renewable sources such as wind or solar, which usually stop generating when the weather changes or night falls.
