Latest Patents
Kenji Sato holds a patent for a "Method for producing vanadium electrolytic solution." This method involves producing a vanadium electrolytic solution that contains highly concentrated and dissolved vanadium. The process includes subjecting a vanadium compound, such as ammonium metavanadate or vanadium pentaoxide, to a reduction operation in the presence of inorganic acids. By repeatedly adding concentrated inorganic acids and the vanadium compound, a tetravalent and pentavalent vanadium solution of 3.4 mol/l is obtained. The resulting vanadium electrolytic solution can be electrolyzed, allowing for the reduction of tetravalent vanadium to trivalent on the negative electrode and oxidation to pentavalent on the positive electrode. This process ultimately forms a discharged couple of trivalent and tetravalent vanadium, resulting in an electrolytic solution suitable for charge-discharge applications in redox batteries.
