摘要

In this paper, brown-millerite type SrCoO_(2.5) ultrafine powders were prepared and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The electrochemical capacitance of SrCoO_(2.5) electrode was examined by cyclic voltammetry, impedance and galvanostatic charge- discharge measurements. The specific capacitance of 168.5 F g~(-1) for SrCoO_(2.5) could be obtained in the range of 0.1-0.7 V.
