Abstract
Redox flow batteries (RFBs) are of recent interest to store harvested renewable energy for improving grid reliability and utilization. in this study, we synthesized and characterized a series of phenyl acrylate-Based UV-cross-linked anion exchange membranes (AEMs) and explored the performance of these AEMs in a model non-aqueous RFB under model conditions. Infrared spectroscopy was utilized to confirm the incorporation of ion carriers in the phenyl acrylate backbone. the electrochemical performance was compared with the commercial Fumasep membrane Fuma-375 based on high stability in non-aqueous solvents, high permeability to the charge-carrying ion, low resistance, low crossover of the redox-active molecules, and low cost. Our results show 55% total capacity retention through 1000 charge/discharge cycles because of low crossover as compared to the Fumasep commercial membrane which retained only 28% capacity. This result is promising in understanding and developing next-generation AEMs for non-aqueous RFBs and other electrochemical systems utilizing organic solvents.
