英文摘要：

The novel vanadium oxide V10O24·2H2O is prepared by sol-gel process and solvent exchange process with the industrial V2O5 powder as the starting materials and a simple peroxidation route. The structure and AC impedance properties of V10O24·12H2O are clarified. It＇s shown that V10O24 ·12H2O has a layer structure with V^5＋ and V^4＋ mixed. New equivalent circuits modeling are proposed to fit the experimental electrochemical impedance spectroscopies, and the fitting results are in agreement with the experimental results. This vanadium oxide is a potential candidate to be used as new power sources materials owing to its structure and electrochemical properties.
