| Résumé |
|
Linear and cyclic voltammetry are common method for the characterization of electrochemical capacitor electrodes. Herewith we describe an approach to modelling voltametric data to provide more detailed information about the electrode under study. The model is based upon the response of a series arrangement of a resistor and capacitor to a linearly changing potential to simulate a double layer capacitor. Also included is a term to account for redox processes in localized domains, electrode instability at the extremes of potential, as well as electrode resistance, each of which represent behaviour commonly encountered in electrochemical capacitors. Development of the model is presented, together with its application to the aqueous manganese dioxide electrode.
