In this situation, the activated carbon derived from coconut shells through a straightforward activation process served as the active material in electrodes for environmentally conscious supercapacitors. Advanced studies using X-ray diffraction (XRD), Ultraviolet (UV) spectroscopy, and Fourier-transform infrared (FTIR) spectroscopy have confirmed that the activated carbon produced through this method exhibits a graphitic phase. Electrodes fabricated from this activated carbon demonstrated a specific capacitance of 8.99 F g−1 in an aqueous electrolyte (1.5 M H2SO4), utilizing expanded graphite sheets as the current collector substrates. Notably, when these electrodes were assembled with a polyethylene separator and used in a configuration that included charge collection from primary, scatter radiation, and electrolyte, they exhibited impressive storage capabilities and energy-power handling capacities. Specifically, they achieved a capacitance of 8.99 F g−1, a specific energy of 4.4860 W h kg−1, and a power density of 53.832 kW kg−1 at a current density of 1 A g−1. These high-performance values were maintained even at 30 A g−1, demonstrating the potential for broad applications in energy and power storage. After irradiation the super capacitor reaching the capacitance of 26.55 F g−1, a specific energy of 13.2484 W h kg−1, and a power density of 158.981 kW kg−1 at a current density of 1 A g−1. To our knowledge, this represents a novel method for creating supercapacitors using activated carbon, which is derived from scatter radiation, to enhance charge collection.
