Tailoring Carbon Nanostructure for High Frequency Supercapacitor Operation
Figure 3
Comparative rate and frequency performance of the capacitors. (a) Normalised current (from CVs) versus scan rate. (b) Normalised capacitance versus scan rate (from CVs) showing the rate of decay of capacitance with increasing scan rates. (c) Bode phase plot. (d) Electrochemical impedance spectroscopy data expressed as Nyquist plots over the frequency range of 10 kHz–0.05 Hz. Inset shows zoom at low impedance.
