| 摘要 |
The present invention relates generally to the production of a vanadium electrolyte, including a mixture of trivalent and tetravalent vanadium ions in a sulphuric acid solution, by the reactive dissolution of vanadium trioxide and vanadium pentoxide powders, the surface area and particle size characteristics being controlled for complete reaction to produce the desired ratio of V(III) to V(IV) ions in the solution. The solution may be suitable for direct use in the vanadium redox battery, or the solution can provide an electrolyte concentrate or slurry which can be reconstituted by the addition of water or sulphuric acid prior to use in the vanadium redox battery.
