Figure illustrates the differential capacitance and surface charge density as functions of electrode potential. The model successfully reproduces the characteristic camel-shaped differential capacitance curve observed in dilute electrolytes . At low potentials, capacitance increases as the electric field enhances ion accumulation near the electrode. As the potential rises further, the capacitance reaches a peak before declining, forming the characteristic "hump" of the camel curve. This behavior arises from the saturation of ion density near the electrode and the associated reduction in the local dielectric constant. Notably, the hump at positive potentials is more pronounced than at negative potentials, as anions can approach the electrode more closely than cations due to differences in hydration properties.
