Abstract
In one embodiment of the present disclosure, a composition for producing a vanadium electrolyte includes a vanadium compound and an ion solution containing vanadium ions and hydrogen ions. In another embodiment, a method for producing a vanadium electrolyte includes obtaining a vanadium compound, and mixing the vanadium compound with an ion solution containing vanadium ions and hydrogen ions.
Claims11
A composition for producing a vanadium electrolyte, the composition comprising:
- a vanadium powder compound in a solid state form having a particle size of more than 50 microns up to 100 microns;
- and
- 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 composition for producing a vanadium electrolyte, the composition comprising:
- a vanadium powder compound selected from the group consisting of trivalent vanadium (V(III)) compound, tetravalent vanadium (V(IV)) compound, pentavalent vanadium (V(V)) compound, and mixtures thereof, wherein the vanadium powder compound is in a solid state form having a particle size of more than 50 microns up to 100 microns;
- and
- an ion solution containing vanadium ions and hydrogen ions, wherein the ion solution includes vanadium ions selected from the group consisting of bivalent vanadium (V(II)) ions, trivalent vanadium (V(III)) ions, pentavalent vanadium (V(V)) ions, and any combinations thereof, 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.
