Abstract

An ultrasonic irradiation method was applied to the sol-gel synthesis of silver vanadium oxides (SVO). Transmission electron microscope (TEM), X-ray diffraction (XRD), thermogravimetry (TG) and differential thermal analysis (DTA) were conducted to research the ultrasonically accelerated reaction between V2O5 gel and Ag2O powder. Galvanostatic discharge experiments showed that the as prepared cathode active material of Ag2V4O11 and Ag(1.2)V3O8 have better electrochemical properties than those synthesized by conventional solid state method.
