(108b) High-Throughput and Data-Driven Strategies for the Design of Deep Eutectic Solvent Electrolytes.
AIChE Annual Meeting
Monday, November 8, 2021 - 12:45pm to 1:00pm
Here, we present our approach to the design of DES electrolytes using high-throughput experimentation and data driven strategies. DES are synthesized by first dissolving the starting components in concentrated stock solutions using volatile solvents. An open-source, automated liquid handling robot then prepares solutions of the components at various molar compositions in multi-well plates. The samples undergo a series of evaporation steps to remove the volatile solvent followed by a final step under vacuum. Liquid samples at room temperature are identified, and the eutectic composition is determined using an in-house constructed and open-source thermal infra-red imaging system able to determine melting points in high-throughput at a fraction of the time compared to traditional methods. Electrochemical characterization to determine conductivities and potential windows is performed in a high-throughput manner using multi-well plates with screen-printed electrodes connected to a standard potentiostat. Finally, approaches to using data science, cheminformatics and engineering metrics to develop design of experiments is presented as a strategy to further probe the chemical space for these materials.
