Aqueous organic-based electrolyte for redox flow battery

Abstract

Disclosed is an aqueous electrolyte for redox flow battery, including a compound of formula (I) and/or an ion of compound (I), and/or a salt of compound (I), and/or a reduced form of the anthraquinone member of compound (I), wherein: X1, X2, X4, X5, X6, X7 and X8 are independently selected from the group consisting of a hydrogen atom, a linear, cyclic or branched, saturated or unsaturated, optionally substituted, hydrocarbon group including from 1 to 10 carbon atoms, a OH group and a —O-A-R1 group, A representing a linear, cyclic or branched, saturated or unsaturated, optionally substituted, hydrocarbon group including from 1 to 10 carbon atoms; R1 representing COOH or SO3H; wherein one and only one of X1, X2, X4, X5, X6, X7 and X8 is OH, and wherein one and only one of X1, X2, X4, X5, X6, X7 and X8 is —O-A-R1.
