7 Thermal Activation of Carbon Felt for the Positive Vanadium Redox Couple Results and Discussion Capacitance The capacitance of each felt was recorded in a 0.5 M H2SO4 solution, and was found to increase with thermal treatment temperature. The surface area of each felt was calculated from the mass of the sample and the geometric area, assuming the fibers perfect cylinders all with the mean diameter for that sample calculated from SEM imaging. Similar capacitance changes are reported in Chapter 6, but are now measured over a range of different treatment temperatures, (Figure 7.2). Figure 7.2: Capacitance of each treated felt measured in 0.5 M H2SO4 from cyclic voltammetry recorded at 100 mVs-1. Of the three samples, the capacitance of C100 increased the most with thermal treatment, confirming the results reported in the previous chapter. The larger increase in capacitance is consistent with the fact that C100 had a much smaller mean crystallite size of 9.63 ± 0.60 Å, compared to 40.00 ± 1.14 Å for G100 and 25.00 ± 0.39 Å for GFE, as calculated from Raman spectroscopy. The smaller crystallite size is indicative of lower graphitic content, and thus C100 is more readily oxidised during the thermal treatment in air. 95PDF Image | Electron Transfer Kinetics in Redox Flow Batteries
