doi:10.3724/SP.J.1077.2008.01193

Abstract

Abstract: The supercapacitor using nano-structured Fe₃O₄ and activated carbon (AC) as electrode materials was developed. Fe₃O₄ magnetic nanoparticles with average particle size of 36nm were synthesized by microwave method using FeSO₄·7H₂O and ammonia as the precipitator. Three kinds of supercapacitors, Fe₃O₄/KOH/Fe₃O₄, AC/KOH/AC, Fe₃O₄/KOH/AC, were prepared using 6mol/L KOH as electrolyte. Cyclic voltammetry (CV), galvanostatic charge-discharge and electrochemical impedance spectroscopy were used to study the performance of the electrodes and the supercapacitors. The results show that the operating voltage of Fe₃O₄/KOH/AC hybrid supercapacitor is 1.2V. When the current density is 0.2mA/cm² and the weight ratio of active materials (Fe₃O₄/AC) is 1.5, the energy density of hybrid supercapacitor is 9.25Wh/kg, which is 53.4% higher than that of AC/KOH/AC capacitor with the same electrolyte.

Key words: nano-structured Fe₃O₄, activated carbon, hybrid supercapacitor, pseudocapacitance, energy density
