Enhanced Performance of a Supercapacitor by Addition of Turbostratic Fractal Graphene to an Activated Carbon Electrode

This research explores the enhancement of supercapacitor performance through the incorporation of a new form of turbostratic graphene (Fractal Graphene, FGA-1) into activated carbon (AC) electrodes. By combining FGA-1 with AC, the electrodes exhibit improved electrical conductivity and enhanced electrolyte diffusion, leading to superior charge storage capability. Material characterization confirms that the FGA-1–AC composite forms a synergistic structure, facilitating better interaction with the electrolyte. The composite electrodes demonstrate significant improvements in specific capacitance compared to AC-only counterparts. Enhanced wettability and optimized diffusion rates were identified as key factors contributing to these improvements. The findings highlight the potential of FGA-1 as an additive for improving the efficiency of carbon-based supercapacitors, providing a foundation for high-performance energy storage solutions suitable for a broad range of applications.
