A low ion-transfer resistance and high volumetric supercapacitor using hydrophilic surface modified carbon electrodes

Abstract

A hydrophilic surface modified carbon electrode shows a good electrolyte affinity with homogeneous dispersibility in water, resulting in low ion-transfer resistance and a uniform and dense electrode to give a high volumetric capacitor. The hydrophilic carbon electrode exhibits a superior capacitance (58 F cm⁻³, 99.3 mF cm⁻²) and is stable up to 5000 cycles.
