Claim 12:
13. A method of delivering electricity comprising the steps of:
a) providing a redox-flow battery according to claim 1 comprising an anolyte and a catholyte; wherein the catholyte comprises ferricyanide and wherein the anolyte comprises reduced anolyte active species;
b) reducing the ferricyanide of the catholyte at the positive compartment (10) to ferrocyanide to obtain a reduced catholyte, while the reduced anolyte active species are oxidized back to their corresponding oxidized state at the negative compartment (20) to obtain an oxidized anolyte;
c) letting flow the reduced catholyte of step (b) into the catholyte reservoir container (12) and the oxidized anolyte of step (b) into the anolyte reservoir container (22); and
d) delivering charge stored in the solid electroactive material in its oxidized state at the catholyte reservoir container by charge transfer between the reduced catholyte and the solid electroactive material in its oxidized state (14) so that the ferrocyanide species of the reduced catholyte of step (c) are oxidized back to ferricyanide by reduction of the solid electroactive material at the cathode reservoir container (12).
