Microfiber electrodes derived from graphite felt were used for the evaluation of charge transfer kinetic constants in a ferrocyanide-based electrolyte, which is a model system for redox flow batteries. Cyclic voltammetry experiments were performed in the presence of 10−2 M or 0.5 M Fe(CN)64−. Within...
