Abstract

Amorphous hydrous nanostructured MnO₂ was synthesized in chemical coprecipitation method by mixing KMnO₄ and manganese acetate aqueous solution using polyethylene glycol(PEG) as disperser.The product was characterized by SEM, TEM, FT-IR, XRD and BET.The results show that the amorphous hydrous nanoparticles with the mean particle size of 10～30 nm were obtained and BET specific surface areas are 160.7 m²/g.Electrochemical characterization was carried out by cyclic voltammetry (CV).Amorphous α-MnO₂·nH₂O in 1 mol/L Na₂SO₄ aqueous electrolyte was proved to be an excellent electrode material for supercapacitor.The specific capacitance of 203.4 F/g was obtained at the scan rate of 4 mV/s in the range of -0.2～0.9 V (vs.SCE).

Key words: supercapacitor, electrode material, MnO₂, cyclic voltammetry
