Figure 9From: Fabrication of high-quality graphene oxide nanoscrolls and application in supercapacitorThe capacitance behavior evaluation of rGO and GNS. The CV curves of rGO and GNS (a) and charge/discharge value of rGO and GNS (b). Nyquist plots of rGO and GNS (c) inset showing the corresponding magnified high-frequency regions; cycle stability of rGO and GNS (d) during the long-term charge/discharge process at current density of 1 A/g after 2,000 cycles.Back to article page
