Disordered materials hold promise for better batteries

January 8, 2014

MIT researchers find that contrary to conventional wisdom, cathodes made of disordered lithium compounds can perform better than perfectly ordered ones. See the MIT News Office for the full story.

Conventional layered lithium and transition metal cathode material (top) and the new disordered material studied by researchers at MIT (bottom) as seen through a scanning tunneling electron microscope. Inset images show diagrams of the different structures in these materials. (In the disordered material, the blue lines show the pathways that allow lithium ions to traverse the material.)
