The Capacitive Behaviors of Manganese Dioxide Thin-Film Electrochemical Capacitor Prototypes
Table 1
Specific capacitance (F/g) of MnO2 thin-film electrochemical capacitor prototypes calculated from cyclic voltammograms (CVs) at different scan rates, and electrochemical impedance spectroscopy (EIS) at the frequency of 10 mHz.
