Waste biomass, such as spent coffee grounds (SCG), presents an abundant and sustainable source of carbon for energy storage other applications. In this study, ultrahigh surface area was synthesized from evaluated electrode material supercapacitors. Using alkali activation process with potassium hydroxide (KOH), the produced nanoporous exhibited BET (∼3600 m2/g) a large pore volume (1.80 cm3 g–1), 95% presence micropores. These structural characteristics significantly enhanced electrochemical performance material, making it suitable use in devices. Electron spin resonance (ESR) measurements were conducted to quantify number radicals, aiming shed light on mechanism behind formation high carbons. The activated tested two-electrode supercapacitor setup ionic liquid electrolyte, demonstrating excellent capacitive properties. It achieved specific capacitances 131 96 F g–1 at 0.5 4 A g–1, respectively. Furthermore, gravimetric density 52 W h kg–1 power 871 1 outperforming commercially available carbons SBET ∼2500 m2/g. testing showed stable across wide voltage window up 3.5 V, minimal pseudocapacitive behavior, confirming its suitability supercapacitors demands. This work underscores potential converting waste biomass into high-performance materials, offering environmentally friendly cost-effective solution. results highlight advantages using grounds-derived supercapacitors, opening pathways further development materials
