Figure 6

Impedance spectroscopies of the supercapacitors based on graphene/MnO 2 composites with different microwave reaction times. All the curves displayed here were measured in the frequency range of 100 kHz to 0.01 Hz. Z′ is the real impedance and Z″ is the imaginary impedance. The insets show an enlarged scale for the impedance spectroscopy images.
