6 Using Individual Carbon Fiber Electrodes to Quantify Effects of Thermal Activation Conclusions Clear differences between the untreated four fiber types (GFE, G100, C100 and Toray) were present in electric double layer capacitance, as well as kinetic performance. Fibers were thermally treated for 1 hour at 450 oC, with a large increase in the electric double layer capacitance observed at C100, G100 and Toray fibers, whilst the electric double layer capacitance for GFE only doubled. Each fiber had clear improvements in kinetic performance, with significantly smaller peak separations observed for each fiber type. The apparent rate constant was then calculated for each fiber before and after thermal treatment. The inherent rate constant could not be directly calculated as only the geometric area of the fiber electrodes was known, not the electrochemically active surface area. EIS measurements were shown to be more accurate for fibers with higher apparent rate constants, where 𝑘0 approaches 0.1 cm 𝑎𝑝𝑝 s-1. This was due in part to the sensitivity of the fitted 𝑘0 value to peak separation, as well as 𝑎𝑝𝑝 the ability to calculate 𝑘0 from EIS without the need to know the radius of the fiber. 𝑎𝑝𝑝 90
