Redox flow batteries are an attractive solution to the problem of grid-level energy storage however low energy densities and high costs are preventing them from becoming commercially viable on a large-scale. A promising approach to address low energy density is the utilization of non-aqueous solvents, assuming well designed charge carriers can utilize the wider potential window and be sufficiently soluble. In this presentation, we will detail the preparation, characterization, and electrochemical performance of metal complexes with polypyridyl ligands along with preliminary results from a bench-scale flow battery system.
