IBM's planning an end to range anxiety with a EV power pack that runs on air and travels 500 miles on a single charge. "Lithium Air" batteries draw oxygen into a nano-structured carbon cathode, where it is stored and reacts with lithium ions and electrons to generate electricity. When you plug the vehicle in, the unmolested oxygen is released back into the air as if it was breathing. The technology's significantly lighter than what's found inside a
