"We now have one which looks very promising," says Wilcke. He won't reveal what material it is but says that several research prototypes have already been demonstrated. And as part of Battery 500, an IBM-led coalition involving four US national laboratories and commercial partners, the hope is to have a full-scale prototype ready by 2013, with commercial batteries to follow by around 2020.

If it works, this would solve a major obstacle with lithium-air batteries, says Phil Bartlett, head of electrochemistry at the University of Southampton, UK. There are other practical issues to address, such as enabling such batteries to cope with moist air. "Lithium in water spontaneously catches fire," he points out. New Scientist

Smart IBM. Why screw around with open source software when the real bucks are in energy.
