Abstract

The invention relates to Redox flow battery comprising at least one electrochemical cell (CEC), a further electrochemical cell (SEC), an electrode disposed or arranged within each electrochemical half-cell, an ion-exchange membrane separating the two electrochemical half-cells of each electrochemical cell and circulating means arranged to circulate a first electrolytic media intended to be received in the battery through an electrochemical half-cell (FCEHC) of each of the at least one electrochemical cell and through an electrochemical half-cell (FSEHC) of the further electrochemical cell. One electrochemical half-cell (SSEHC) of SEC comprises at least one redox couple M^y/M^x insoluble in a second electrolytic media intended to be received in the SSEHC, according to formula 1 M^y + pe^- ↔ M^x, formula 1, wherein x and y are oxidation number. The FSEHC is arranged to reduce an oxidized state C^b to a reduced state C^c, and conversely, of at least one redox couple C^b/C^c comprised in the first electrolytic media according to formula 2 C^b + ne^- ↔ C^c, formula 2, wherein b and c are oxidation number. An absolute potential difference |ΔE₁| between a redox potential E(C^b/C^c) of the at least one couple C^b/C^c, in a given or predetermined first electrolytic media, and a redox potential E(M^y/M^x) of the at least one couple M^y/M^x, in a given or predetermined second electrolytic media, is lower than or equal to 0.8 V.
