摘要：

A method for the industrial production of the solution for a vanadium redox flow battery was established. Ammonium trivanadate was produced by condensing ammonium methavanadate recovered from boiler soot in sulfuric acid solution, which was then separated as the solid matter from the solution. The ammonium trivanadate was calcined in air to exclude ammonium and to produce vanadium pentoxide. Vanadium trioxide without ammonium was produced by reduction with hydrogen. Finally, vanadium pentoxide and vanadium trioxide in a molar ratio of 1 : 3 was added into distilled water and dissolved by adding concentrated sulfuric acid which was produced from a flue gas desulfurization facility, resulting in the electrolyte for the vanadium redox flow battery.
