摘要： Non-aqueous redox flow battery (RFB) comprising: a positive compartment in which a positive electrode is positioned and in which a positive non-aqueous liquid electrolyte is caused to flow; a negative compartment in which a negative electrode is positioned and in which a negative non-aqueous liquid electrolyte is caused to flow; an ion-exchange membrane positioned between the positive compartment and the negative compartment in which: said positive non-aqueous liquid electrolyte comprises a solution of copper triflate or tetrafluoroborate complexes [Cu(l) or Cu(ll)] in at least one organic solvent; said negative non-aqueous liquid electrolyte comprises a solution of at least one benzothiadiazole or a derivative thereof in at least one organic solvent. Said non-aqueous redox flow battery (RFB) may advantageously be used in devices which require a moderate to large power output (e.g., about 100 kW - 100 MW) for a number of hours (i.e. > 1 hour) such as, for example, devices for storing energy derived from industrial plants or from alternative energy sources (such as, solar or wind energy) for subsequent use (for example, for domestic use) or for sale.
