The greater variety of formulae used with CV datasets compared to GCD datasets was due to the combination of the incorrect formula used to calculate total capacitance in addition to the different interpretations of "specific capacitance" outlined in Section 1.2. This incorrect analysis was due to confusion when using the area of the entire CV cycle during the analysis. This data reinforces several points stated previously. Firstly, one needs to clearly define what "specific capacitance" means when reporting values for this metric to avoid confusion. Secondly, the community needs to be reminded of the correct formula for calculating specific capacitance from CV data, as 29% of participants used an incorrect formula in this study. Finally, the three groups of specific capacitance values are less visible for File 4 as fewer participants reported values for this dataset due to its non-ideal behaviour. This further illustrates that it may be more suitable to characterise energy storage devices with non-ideal charge storage mechanisms with other, more appropriate performance metrics.
