Where, "C" represents the capacitance, which signifies the accumulated charge(s) at the interface. The equation involves "ε", denoting the dielectric constant of the electrolyte, the effective thickness of the electrical double layer, and "S", which stands for the surface area of the electrode interface. Typically, the specific capacitance (Cm) can be determined through two approaches: (i) By integrating the area under a cyclic voltammetry (CV) curve, (ii) By analysing the slope of the galvanostatic charging/discharging curve. For these methodologies, the relies on equation , while the latter employs equation .
