Supercapacitors have an asymmetric electrode potential and charge due to nonelectrostatic electrolyte interactions
In recent years we have built up a theoretical framework which aims to explain ion specific effects observed in colloids at high salt concentrations. Our approach adds nonelectrostatic ion interactions (ion dispersion energies) alongside the usual electrostatic interactions of the ions.Using these techniques we have explored the impact that ion specificity may have on supercapacitors. Our model uses graphite electrodes at constant potential difference in 1.2M Li salt dissolved in propylene...[Show more]
