A new study, led by University of Illinois Urbana-Champaign materials science and engineering professor Paul Braun, postdoctoral research associate Beniamin Zahiri, and Xerion Advanced Battery Corp. director of research and development John Cook, demonstrates how control over the atomic alignment of solid materials can improve the cathode-solid electrolyte interface and stability in solid-state batteries. The results are published in the journal Nature Materials.

"With batteries, it's not just materials that are important, but also how the atoms on the surfaces of those materials are arranged," Zahiri said. "Currently, solid-state battery electrodes contain materials with a large diversity of surface atom arrangements. This leads to a seemingly infinite number of electrode-solid electrolyte contact interface possibilities, all with different levels of chemical reactivity. We are interested in finding which arrangements lead to practical improvements in battery cycle life, energy density and power."

The researchers said an electrolyte's stability controls how many charging and discharging cycles a battery can handle before it starts to lose power. Because of this, scientists are in a race to find the most stable electrolyte materials.
