Figure 6From: Solution growth of NiO nanosheets supported on Ni foam as high-performance electrodes for supercapacitorsElectrochemical characterizations of the NiO nanosheets on Ni foam as electrodes for supercapacitors. (a) CV curves at various scan rates ranging from 2 to 50 mV s-1. (b) Average specific capacitance at various scan rates. (c) Charging/discharging voltage curves at various current densities ranging from 5 to 25 A g-1. (d) Specific capacitance of NiO nanosheets at various discharge current densities.Back to article page
