Adsorption of a typical electrolyte in CDC-based supercapacitors. (A) Typical snapshots of the four different adsorption modes identified in CDC electrodes (gray sticks, C–C bonds; red spheres, BMIM⁺ cations; green spheres, PF₆^– anions; blue spheres, acetonitrile molecules; gray spheres, C atoms which are in the coordination sphere of the central molecule). (B) Concentration of the various species in the four different adsorption modes at null voltage. (C) Counter-charge accumulated at the surface of the electrode (per ion) as a function of the degree of confinement of the ion for an applied voltage of 1 V.
