Preparation method for commercial vanadium battery electrolyte
ActiveCN103606694AHigh purityLimited service lifeIndirect fuel cellsAcid electrolytesSocial benefitsHydrogen
The invention discloses a preparation method for commercial vanadium battery electrolyte. According to the preparation method, vanadium electrolyte is prepared by one step through a chemical method; the preparation method comprises the following steps: dissolving raw materials containing vanadium by using an alkali; adjusting a pH (Potential of Hydrogen) value by acid-alkali regulation; repeatedly precipitating the vanadium to remove impurity elements; then roasting to obtain an oxide of the vanadium; finally, dissolving the oxide of the vanadium by using concentrated sulfuric acid to obtain the vanadium electrolyte. With the adoption of the method, impurities including iron, chrome, silicon, manganese and the like can be removed effectively and a process flow is shortened; the vanadium yield is improved, the impurity content is reduced and the process flow is shortened; the product purity can also be improved. The preparation method for the commercial vanadium battery electrolyte has important meanings on production technology levels and market competitiveness of the vanadium electrolyte; the method has good economic benefits and social benefits.
