摘要

摘要: 以高纯V₂O₅为原料,以H₂O₂还原V₂O₅的方法制备钒电池用VOSO₄,并对制备工艺及其反应机理进行了研究。通过计算,得到了制备VOSO₄的反应焓变和吉布斯自由能变化,并用制备的VOSO₄作为钒电池的活性材料进行了充放电性能测试。结果表明:生成VOSO₄的反应为放热反应,且该反应促进了V₂O₅的溶解。该法生产工艺简单、绿色环保,V₂O₅:H₂O₂:H₂SO₄的最佳摩尔比为1:1.2~1.4:2.4~2.5。制备出的VOSO₄中V⁴⁺的含量占总钒量的99.66%、V⁵⁺含量仅占0.34%,具有良好的充放电性能,可以作为钒电池电解液的活性材料。

Abstract: VOSO₄ used for vanadium battery was prepared by reduction of high purity V₂O₅ with H₂O₂,and the preparation technology and reaction mechanism were studied.The enthalpy and Gibbs free energy change of the reaction for preparing VOSO₄ were calculated,and the charge and discharge performance testing were performed using the prepared VOSO₄ as active material of vanadium battery.The results show that it's an exothermic reaction for VOSO₄ formation and the dissolution of V₂O₅ is promoted by the reaction.This technology is characteristic of simple,green and environment-friendly with the best mole ratio of V₂O₅:H₂O₂:H₂SO₄=1:1.2~1.4:2.4~2.5.The V⁴⁺ content in the obtained VOSO₄ accounts for 99.66% of total vanadium amount,with V⁵⁺ occupying 0.34%.The prepared VOSO₄ has a good charge and discharge performance,which can be used as active material of vanadium battery electrolyte.
