Little more on development of a Li-Air battery and a couple of the pending issues. One problem is that in order to provide the same energy as, say, gasoline, lithium-air batteries require more space—although not much more weight—than the fossil fuel. Whittingham predicts that the technology will be used for large, stationary energy-storage applications rather than for portable batteries. Another problem is that lithium-air batteries are chemically delicate: The lithium gets diverted into dead-end reactions with water or carbon dioxide in the air, so the electrodes in any future battery may need to be sealed or filtered so that they interact only with dry air and the electrolyte, an added expense and complication. spectrum.ieee.org
