Figure 8

The electrochemical properties of the RGO-Ni(OH)2//RGO-7-10 ASC:
(a) CV curves at different scan rates, (b) GCD curves at different current densities, (c) Ragone plots of different asymmetric supercapacitors and (d) cycling performance measured at a current density of 15 A g−1. All data in this figure are based on the asymmetric device with total mass of both electrodes.
