Recent advances in ion selectivity with capacitive

This high selectivity towards the divalent species is in good agreement with earlier works, and can be explained by the Nernst–Planck equation (Section 4. Theory ), in which both show a strong effect of the valence on the transport and on the concentration of ions on the electrode ( Fig. 8C ). 24 At low currents and high flow rate, the
