▎ 摘  要

NOVELTY - Fastly regulating valence state of vanadium solution based on high current pulse process, comprises using high-valence state vanadium electrolyte solution, low-valence vanadium electrolyte solution and vanadium electrolyte solution with unbalanced valence as main raw materials, carrying electrolysis in electrolytic cell by adopting the pulse process to obtain the electrolyte solution whose vanadium ion valence state meets the requirements of vanadium battery; the electrolytic cell is composed of positive and negative half-cells, the two half-cells are separated by a diaphragm, the electrode inserted in the positive half cell is connected to the anode of the DC pulse power supply, the electrode inserted in the negative half cell is connected to the cathode of the DC pulse power supply, and the pulse electrolysis parameters are controlled for electrolysis. USE - The method is useful for fastly regulating valence state of vanadium solution based on high current pulse process. ADVANTAGE - The method: is simple and easy to operate; can quickly adjusts the vanadium valence state of the electrolyte solution, can obtains the electrolyte solution with the specified vanadium valence state, and can meets the use requirements in different situations; overcomes technical limitations of chemical reduction, low-current DC electrolysis and other processs; and has mild conditions, short time consumption and easy control of valence state.
