In the present work, a feasible approach for developing a carbon derivative exhibiting all the promising features of a superior electrode material is reported. Nitrogen and Sulfur are strategically incorporated into the carbonaceous material along with Potassium-based activation, such that additional pseudocapacitance, along with an enhanced surface area are achieved. Carbon derived from charcoal is co-functionalised with Nitrogen and Sulfur via a two-step pyrolysis technique, resulting in a material that exhibits improved surface area of 1488.8m2g?1 and enhanced electrochemical performance. It showcases a gravimetric capacitance of 689Fg?1 and 295Fg?1 at 1Ag?1, corresponding to the three and two-electrode setups respectively. A gravimetric capacitance of 425Fg?1 is maintained at a high current density of 50Ag?1 with a capacitance retention of 61.6 %. A sustained energy density of 20.50W h kg?1 at a power density of 3.1kWkg?1 is achieved by this material with a stability of 94 % for 5000 cycles at 2Ag?1. In addition, coin cells fabricated with the as-prepared material demonstrated the real-world feasibility by illuminating LEDs of different colors. 2026 Elsevier B.V.
