Physical Sciences Incorporated (PSI) proposes to develop, characterize, and evaluate new ionic liquids (ILs) and eutectics with enhanced physical and chemical properties for electrochemical supercapacitor applications. The ILs will be synthesized with high yield and high chemical purity as confirmed by standard analytical techniques. Results from differential scanning calorimetry, viscosity, ionic conductivity, and cyclic voltammetry experiments will validate that these ILs/eutectics can function effectively as electrolytes over a broad temperature range (±70 deg C) and large electrochemical window (±2V). The most promising electrolyte will be studied in an electrochemical system as a proof-of-concept. In Phase II, we will continue to develop and characterize innovative ILs and eutectic formulations. The new materials will have reduced viscosity, and an enhanced thermal stability, ionic conductivity, and electrochemical window compared to those studied in Phase I. Performance of the ILs/eutectics will be assessed in multiple electrochemical systems such as batteries, supercapacitors, and electrochromics. By the completion of Phase II, we will demonstrate ~ 10^3 reversible cycles of an electrochemical device using an IL/eutectic electrolyte at -70 deg C. Cost analysis and design specifications will be performed for limited rate production of several candidate materials.
