Abstract

The ability of unmodified or PbO₂ coated spectral graphite (SG), to act as positive electrode in an all-vanadium redox flow battery was tested. Our results showed that the unmodified SG requires simple pretreatment and is efficient in terms of current due to a large active area, 4 times greater than the geometrical one. The PbO₂ deposits were grown on surfaces that previously received only basic treatment but present a poor stability. In all experiments, large separations of anodic and cathodic peak potentials (between 118 and 1015 mV) were observed, proving the irreversibility of the V^V to V^IV redox couple on all studied materials.
