The research programme proposed in this Fellowship application details a plan to develop alternative electrodes for RFBs using sustainable resources. RFBs often employ carbon felts as electrodes, prepared from non-sustainable polyacrylonitrile (PAN), and their activity towards the redox reactions is poor, leading to low efficiency systems. I propose to use electrospinning, a very versatile processing technique that allows for fine control of the features of the materials prepared, to produce a new generation of freestanding electrodes

with unique tailored properties that will increase the power density and voltage efficiency of RFBs.
