Abstract Details

2020, Master of Sciences, Case Western Reserve University, Chemical Engineering.
Deep eutectic solvents (DESs) and ionic liquids (ILs) are emerging classes of tunable solvents with potential applications in electrochemical energy storage systems. These solvents exhibit favorable properties including high solvent strength, wide electrochemical windows, and lack of flammability. However, high viscosity and low conductivity has thus far limited their practical application. Additionally, their heterogenous liquid structure and lack of basic structure-function design rules presents challenges in understanding fundamental properties. Here, standards for consistent preparation, handling, and characterization of DESs are proposed. The impact of chemical structure on DES physical, solvation, and transport properties is evaluated demonstrating anion substitution as a future pathway for solvent tuning. A preliminary study investigating the feasibility of utilizing quinones in DESs demonstrates anomalous previously unreported redox behavior. Finally, the electrode-electrolyte interface of ammonium ILs is probed. Long alkyl chains are demonstrated to stabilize accumulation of anions at the electrode surface.
