This $282,020 project grant from the National Science Foundation's Division of Chemical, Bioengineering, Environmental, and Transport Systems will fund research at Northern Illinois University from October 2022 to September 2025. The research aims to advance understanding of reversible sodium hydrosulfide formation in hybrid electrolytes to enable high energy density sodium-sulfur battery technology. Specifically, the university will conduct fundamental studies using X-ray scattering characterization and electrochemical reaction kinetics analysis to elucidate the multistep phase transformation pathways of sodium-polysulfide chemistry in enabling electrolyte systems. The research also includes in situ characterization at the U.S. Department of Energy's Argonne National Laboratory to understand electrolyte solvation structure evolution and electrode reaction thermodynamics and kinetics. Insights gained from this work could help develop high energy density batteries using abundant materials to power electric vehicles, grid-scale energy storage, and other applications.
