Abstract
In recent years, attention has been focused on use of various metal oxides as supercapacitor electrodes for high-power applications1-4. Theenergy storage mechanism with these materials is based mainly on fast faradaic redox reactions, which occur at the interface between the oxide and the electrolyte4-5, giving rise to the so-called “pseudo-capacitance”. The great advantage in this case is that the specific capacitance which can be obtained is higher than for electrochemical capacitors where the charge is only stored in the double layer. The characteristics required for the use of a metal oxide as capacitor electrode are a pseudo-capacitive behavior, a large specific surface area, a high conductivity and electrochemical stability.
