MnO₂ with a high surface area of 177 m²/g as electrode for electrochemical capacitor was prepared with Ag foil as the catalyst at room temperature.The results of XRD and SEM showed that the MnO₂ is α-MnO₂ microspheres with cactus-like morphology composed of nanofibres.AC impedances,cyclic voltammetry and constant current charge-discharge tests indicated that α-MnO₂ microspheres had an excellent electrochemical capacitance with the highest capacitance of 187.1 F/g and retained 90% of the initial capacity over 1 000 cycles within the potential range of 0~0.8 V versus SCE in 1 mol/L Na₂SO₄.
