Claims13
A method for producing a vanadium electrolyte, the method comprising:
- obtaining a vanadium powder compound in a solid state form having a particle size of more than 50 microns;
- and
- mixing the vanadium powder compound with an ion solution containing vanadium ions and hydrogen ions, wherein the ion solution includes at least one group of vanadium ions having a different oxidation state than the oxidation state of the vanadium ions produced by dissolving the vanadium powder compound.
A method for producing a vanadium electrolyte, the method comprising:
- obtaining a vanadium powder compound in solid state form having a particle size of more than 50 microns, wherein the vanadium powder compound is selected from the group consisting of trivalent vanadium (V(III)) compound, tetravalent vanadium (V(IV)) compound, pentavalent vanadium (V(V)) compound, or mixtures thereof;
- and
- mixing the vanadium powder compound with an acidic vanadium ion solution, wherein the vanadium ion solution is selected from the group consisting of bivalent vanadium (V(II)) ions, trivalent vanadium (V(III)) ions, and pentavalent vanadium (V(V)) ions, or any combinations thereof, wherein the vanadium ion solution includes at least one group of vanadium ions having a different oxidation state than the oxidation state of the vanadium ions produced by dissolving the vanadium powder compound.
