Electrochemical measurements of an as-assembled a-CSH-700//a-CSH-700 symmetric supercapacitor in a 6 M KOH electrolyte: (a) CV curves of the cell operated in different voltage windows at scan rate 50 mV/s; (b) galvanostatic charge/discharge curves of the cell at various current densities; and (c) specific capacitances for the supercapacitor at different current densities. (d) Cycling stabilities of the devices at a current density of 10 A/g. (e) Ragone plot. (f) First two cycle charge-discharge and last two charge-dischage plots.
