<p>An all-vanadium redox charge cell is disclosed. The cell has a negative charge compartment having a negative charge electrode for charging a charge anolyte in electrical contact with said negative charge electrode, the charge anolyte comprising an electrolyte containing trivalent and/or tetravalent vanadium ions, a positive charge compartment having a positive charge electrode for charging a charge catholyte in electrical contact with said positive charge electrode, the charge catholyte comprising an electrolyte containing tetravalent vanadium ions, and an ionically conducting charge separator disposed between the positive and negative charge compartments to provide ionic communication between the charge catholyte and the charge anolyte. The positive charge electrode is selected such that it is stable in the charge catholyte in the charge potential range during oxidisation of tetravalent vanadium ions to pentavalent vanadium ions at the positive charge electrode and the negative charge electrode is selected such that it is stable in the charge anolyte in the charge potential range during reduction of tetravalent and trivalent vanadium ions to divalent vanadium ions at the negative charge electrode. Also disclosed is an all-vanadium redox dual battery system which incorporates the above all-vanadium redox charge cell.</p> |
