Inventing Batteries from Air: Scientific American

Inventing Batteries from Air: Scientific American: "One of the most exciting prospects is lithium-air technology, a decade-old idea that many think could be the ultimate battery. Today's electric cars max out at 100 miles on a single charge, but lithium-air could theoretically make distances of 400 and 500 miles possible. Its cells pulse with so much energy, in fact, that it rivals gasoline."
