Abstract

Since companies have declared their commitment to operating with 100% renewable energy, developing electrical storage systems using natural eco-friendly resources is in full swing. Efforts to replace existing materials in core electrode materials are accelerating, but the use of toxic chemicals in the complex production process is decreasing its value. This study presents a unique porous carbon electrode made of pure biomass DNA wastes synthesized simply via a single step of hydrogelation-calcination without activation through carbonization. Electrochemical analysis of the electrodes revealed energy storage performance with an outstanding specific capacitance of 563.34 F g⁻¹ at 1 A g⁻¹. The QSSC exhibited an energy density of 13.05 Wh kg⁻¹ and a power density of 486.67 W kg⁻¹. It was connected to a solar panel for renewable energy storage and successfully powered a digital clock and LEDs (Light Emitting Diode), demonstrating the potential of advanced sustainable and cost-effective energy storage solutions.
