Unlike the specific capacitance results reported from GCD datasets (Section 1.2), the specific capacitance results from CV datasets can be divided into 3 distinct groups based on three different formulae used. For the upper group, the specific capacitance was calculated using Equation , stated above as Cg,2. For the middle group, the specific capacitance was calculated using an incorrect formula that differs from Equation with the factor of two on the numerator missing. For the lower group, specific capacitance was calculated using Equation 3, stated above as Cg,1.
