6 Using Individual Carbon Fiber Electrodes to Quantify Effects of Thermal Activation To determine if the changes in the capacitance and hence electrochemically active surface area resulted in improved electron transfer kinetics, the electrochemical behaviour of the Fe(CN) 3− / Fe(CN) 4− redox couple at the carbon fiber samples was measured using cyclic 66 voltammetry (Figure 6.2). Figure 6.2: a) Cyclic voltammograms of single carbon fiber microelectrodes recorded at 100 mVs-1 in a 1 M KNO3 solution containing 1 mM K3Fe(CN)6 and 1 mM K4Fe(CN)6. b) peak separation at different sweep rates for each fiber type, recorded in a 1 M KNO3 solution containing 1 mM K3Fe(CN)6 and 1 mM K4Fe(CN)6. It has been demonstrated that at cylindrical electrodes the peak potential separation is related to the activity of an electrode towards a redox reaction [142]. Smaller peak separation at a given sweep rate and radius indicates faster electrode kinetics and a larger apparent rate constant. It can be seen from (Figure 6.2b) that the GFE electrodes typically had the smallest peak separations, followed in order by C100, G100 and Toray (not shown as no peaks were present in the recorded CVs). 80PDF Image | Electron Transfer Kinetics in Redox Flow Batteries
