| titleOfInvention | Method for producing vanadyl sulfate battery electrolyte by using vanadium-containing acid leaching solution |
| abstract | The invention provides a method for producing vanadyl sulfate battery electrolyte by using vanadium-containing pickle liquor, which comprises the following steps: adding a reducing agent into the vanadium-containing pickle liquor for reduction reaction, and after the reaction is finished, adjusting the pH of the solution to 1.5-4.0; selecting an extracting agent consisting of a phosphoric acid extracting agent, alcohol and solvent oil, and performing multi-stage countercurrent primary extraction on the solution to obtain a primary extracted organic phase and a primary raffinate; carrying out multi-stage counter-current back extraction on the primary extracted organic phase to obtain a primary lean organic phase and a primary back extraction solution; adjusting the pH value of the primary stripping solution to 1.5-4.0, selecting a phosphoric acid extracting agent, alcohol and solvent oil to form an extracting agent, and performing multi-stage countercurrent secondary extraction on the primary stripping solution to obtain a secondary extracted organic phase and a secondary extracted water phase; carrying out multi-stage counter-current back extraction on the secondary extracted organic phase to obtain a secondary lean organic phase and a secondary back extraction solution; and secondary stripping solution is subjected to precise filtration or deep oil removal to obtain a high-purity vanadyl sulfate battery electrolyte product. |
