6 Using Individual Carbon Fiber Electrodes to Quantify Effects of Thermal Activation Therefore, it is possible to increase 𝐴𝑒𝑎 by either increasing the roughness of the surface (likely through the production of pores) or by improving the wettability of the surface. Both of these factors directly influence the electric double layer capacitance of the electrodes. The importance of accounting for the differences in electrochemically active surface area is described further in literature, in terms of the exchange current density which is directly related to the inherent rate constant [177]. It is possible to identify differences in wettability by comparing physical area as measured by BET, relative to electric double layer capacitance. Increases in physical area should be shown with BET analysis, but if the electrolyte cannot wet into the new pores the electric double layer capacitance will remain unchanged. In this work, thermal activation is used as a model procedure, introducing oxygen groups to the graphite felt surface. We show that by using cyclic voltammetry and electrochemical impedance spectroscopy at single fibers, we can separate the performance effects from the surface area, wettability, inherent rate constant and conductivity. 75PDF Image | Electron Transfer Kinetics in Redox Flow Batteries
