A systematic way to find battery materials

Lithium-ion batteries have become a leading energy source for everything from smartphones and laptops to power tools and electric cars, and researchers around the world are actively seeking ways to nudge their performance toward ever-higher levels. Now, a new analysis by researchers at MIT and the University of California at Los Angeles (UCLA) has revealed why one widely used compound works particularly well as the material for one of these batteries' two electrodes -- an understanding they say could greatly facilitate the process of searching for even better materials.
