IBM places big bet on lithium-air batteries

Abstract:
IBM hopes to exploit its expertise in supercomputing, nanotechnology, green chemistry and materials science to develop lithium-air technology. As Narayan explained it me, such batteries could pack 10 times the energy density of the lithium ion batteries now used in electric cars because they use air drawn in from outside the battery as a reactant. That means lithium-air storage devices weigh less than lithium-ion batteries, which also improves performance of electric cars. It's not a new idea, but no one has yet created a rechargeable lithium air battery.
