摘要：

A novel solution process using vanadium oxide sol with acetone was developed and V2O5/carbon composite cathodes capable of high rate charge/discharge were fabricated. It was found that the sol condition affects the electrochemical performance of the cathodes. This report presents the fabrication process and the electrochemical performance of the cathodes, and the morphological property of the colloidal particle such colloidal particle size, density and shape at various concentrations. The correlation between the electrochemical performance of the cathodes and the colloidal character of the sol is discussed. (C) 2002 Published by Elsevier Science B.V.
