(a) Illustration of fullerene C₆₀ microbelts (FMBs) crystals synthesis and their conversion into mesoporous carbon microbelts (MCBs), (b) Cyclic voltammograms (CV) of the prepared materials at a fixed scan rate of (5 mV s⁻¹), (c) CV curves vs. scan rate as a typical example of the optimal sample (FMB_900). (d) Comparison of calculated specific capacitance of prepared samples (FMB, FMB_900, and FMB_2000). (e) Typical example of charge−discharge (CD) curves vs. current density (1−10 A g⁻¹). (f) Variation of calculated specific capacitance vs. current densities showing the high rate performance of mesoporous carbon microbelts, and (g) Capacitance retention up to 10,000 charge−discharge cycles.
