This $246,549 National Science Foundation project grant supports fundamental research at Utah State University to advance all-solid-state lithium battery technology. The NSF Division of Civil, Mechanical, and Manufacturing Innovation awarded this funding under the Engineering program (CFDA 47.041) on September 1, 2022 for completion by August 31, 2025.
The grant will fund integrated experimental and computational research to investigate how mechanics can be harnessed to achieve uniform and stable lithium plating and stripping in solid-state battery anodes. Researchers will conduct correlated mechanical, electrochemical and morphological characterization of lithium plating/stripping with residual stress measurements. Molecular dynamics simulations will quantify stress and geometric effects on the lithium-solid electrolyte interface at the atomic scale. A continuum model incorporating stresses, interfaces and chemical reactions will also be developed. Insights will inform a mechanics-driven design approach for anode interfaces to engineer plasticity-assisted uniform lithium deposition and dissolution. Results aim to advance all-solid-state battery technology for electric vehicles and national sustainability goals.
