Effect of electrolyte cation on the charge storage mechanism of manganese dioxide for electrochemical capacitors

The performance of manganese dioxide (γ-MnO2) as an electrode material in electrochemical capacitors is examined in aqueous electrolytes of 0.5 M Li2SO4, Na2SO4, K2SO4 or MgSO4. Performance and mechanistic analysis is conducted using cyclic voltammetry and step potential electrochemical spectroscopy...
