Figure 3.

The dependence on the reduced applied voltageis shown for: the total reduced capacitance(solid black lines), graphene’s reduced quantum capacitance(dashed red lines), and the reduced capacitance of the electric double layer(dotted blue lines), in the NaF aqueous solutions with the reduced salt concentrations of= 1 (thick lines) and 105(thin lines)
