Accelerate Material Discovery and Expand Chemistry Space for Aqueous Organic Redox Flow Batteries

Aqueous organic redox active materials have recently shown great promise as alternatives to transition metal ions as energy bearing active materials in redox flow batteries for large-scale energy storage due to their structural tunability, cost effectiveness, availability, and safety features. However, development to date has been limited to a small palette of aqueous soluble organics. This presentation will provide an overview of a data-driven approach to accelerate the discovery and development of aqueous organic redox-active molecules for flow batteries, including database curation, structure-property correlation, and automated property characterization and performance testing. This presentation will also use fluorenone as an example to showcase how a natively redox-inactive molecule can be tuned to possess two-electron redox reversibility through hydrogenation and dehydrogenation.
