where 𝐶 𝑇 (F) is the total capacitance as calculated in the previous section and Mcell (g) is the total mass of the two electrodes in the cell (i.e., Mcell = me,1 + me,2; where me,1 and me,2 are the masses of the two electrodes, respectively). Cg,1 has units of F g -1 . This equation normalises the cell capacitance by the total mass of the two electrodes in the cell. In this study, only the masses of the electrodes in each cell were provided to participating groups. One group recommended that specific capacitance be calculated using the total mass of the overall cell including the separators, current collectors, casings, and other components.
