A team of scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory discovered an intriguing cooperative behavior that occurs among complex mixtures of components in electrolytes in batteries. Electrolytes are materials that move charge-carrying particles known as ions between a battery’s two electrodes, converting stored chemical energy into electricity.

The team found that combining two different types of anions (negatively charged ions) with cations (positively charged ions) can significantly improve the overall battery’s performance. This suggests that careful selection of ion mixtures can enable battery developers to precisely tailor their …
