Lei Cheng

Chemist

Biography

Lei Cheng is a chemist in Argonne’s Materials Science division and a technical lead for beyond lithium-ion and solid-state electrolyte research at the Argonne Collaborative Center for Energy Storage Science (ACCESS). She also serves as a focus area lead for the Liquid Solvation Science thrust of the Joint Center for Energy Storage Research (JCESR). JCESR is an Energy Innovation Hub under the U.S. Department of Energy that focuses on advancing battery science and technology.

Cheng’s research focuses on using multiscale computational methods to study material structures and properties for energy storage applications, and surface reaction mechanisms at solid-liquid electrolyte interfaces of batteries, in heterogeneous catalysis and in the atomic layer deposition processes.
