Improving the voltage and lifetime in aqueous redox flow batteries utilizing the organometallic [Fe(bpy)3]2+/3+

Department of Physical and Environmental Sciences, College of ScienceLong term battery storage is needed for renewable energy sources to buffer their variable output. Redox flow batteries (RFBs) have the potential to store large amounts of energy for on-demand power generation. Current issue: low energy density due to poor solubility of the active species and low voltage outputs. Robust, high voltage catholytes are needed. Iron (II/III) tris-2,2’-bipyridine ([Fe(bpy)3]2+/3+) is a suitable catholyte. This work introduces a new way to synthesize [Fe(bpy)3]2+ and methods to improve performance.This research was supported by funding from The Welch Foundation.
