Abstract: PROBLEM TO BE SOLVED: To provide a new method for preparing VOPO4 .2H2 O having small sized particles while remarkably reduced reaction time. SOLUTION: The method includes a process for mixing V2 O5 ,H3 PO4 and H2 O with each other in a molar ratio V2 O5 :H3 PO4 :H2 O of 1:(40-50):(500-610), a process for treating the mixed solution with ultrasonic wave, a process for washing the material obtained by ultrasonic treatment and vacuum-filtering, and a process for drying and recovering the material obtained by the filtration.

Abstract: PROBLEM TO BE SOLVED: To provide an oxidation-reduction ultrahigh-capacitance capacitor which is provided with an electrode and a separator which are formed in one piece by using a high-molecular electrolytic film so as to simplify a manufacturing process and to reduce interface resistance between the electrode and separator, after an electrode plate is manufactured by conducting direct coating to a charge collector, or by bonding the collector and an electrode active material utilizing heat and pressure, for applying polyaniline doped with a new dopant to the electrode active material, and to provide its manufacturing method. SOLUTION: The electrode active material 302 formed of conductive polyaniline powder and the charge collector 301 are integrally joined to form a positive electrode plate, the electrode active material 302 formed of the conductive polyaniline powder and the charge collector 301 are integrally joined to form a negative electrode plate, and a high-molecular electrolytic film 501 is provided between the positive electrode plate and negative electrode plate.
