This Project Grant award from the National Science Foundation (NSF) Division of Chemistry, under the Mathematical and Physical Sciences (CFDA 47.049) federal grant program, provides $210,000 to support a collaborative research project between Oregon State University and the University of California, Riverside. The project, led by Professors Ji and Fang of Oregon State University and Professor Greaney of UC Riverside, aims to explore the roles of local solvation structures in expanding the stability of water-based electrolytes for energy storage technologies. Using a combination of femtosecond stimulated Raman spectroscopy and ab initio molecular dynamics simulations, the researchers will investigate how the chemical environment with various cations and anions affects the electrolytic properties of aqueous solutions. The project seeks to elucidate key factors that dictate the hydrogen evolution and oxygen evolution reactions in aqueous electrolytes, with the broader goal of developing a platform to rationally design aqueous electrolytes with expanded electrochemical stability windows for applications in safe grid-scale storage batteries and green hydrogen production.
