1. dissolve the method that barium oxide prepares electrolyte for vanadium cell, it is characterized in that, comprise the following steps:

  • 1) high-purity ammonium vanadate is calcined 0.5-5h under 200-800 DEG C of high temperature, obtain calcined product;

    2) step

         1) gained calcined product naturally cools with stove, passes into the mist of protective gas and oxygen, obtain barium oxide V during cooling xo y, wherein x ﹕

    y=2 ﹕

    3 ~ 2 ﹕

    5;

    3) at 30 ~ 90 DEG C, by barium oxide V xo ybe dissolved in dilute sulfuric acid, obtain electrolyte for vanadium cell.
