NEW AQUEOUS ORGANIC-BASED ELECTROLYTE FOR REDOX FLOW BATTERY

摘要

The present invention concerns an aqueous electrolyte for redox flow battery, comprising 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 comprising 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 comprising 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, andwherein one and only one of X¹, X², X⁴, X⁵, X⁶, X⁷ and X⁸ is -O-A-R¹
