Scientists decode mystery behind battery cathode's success

Lithium iron phosphate is a material known to work well as a cathode in batteries. But scientists have not understood why, because, in theory, it should not work as well as it does. Researchers at the University of California at Los Angeles and the Massachusetts Institute of Technology found that the compound actually absorbs lithium in a single-phase process. Understanding the process could help others discover materials that were previously overlooked, the researchers say.
