The electrochemical energy storage behavior of the fabricated carbon materials was first evaluated in symmetrical supercapacitor device architecture. The identical electrodes were assembled in Swagelok type cells using 6.0 M aqueous KOH electrolyte and cycled in a voltage window of 0.0-0.8 V. The cyclic voltammograms (CVs) of the fabricated supercapacitors devices with 1C, 2C
