Abstract
The present invention relates to a method for recycling an aqueous electrolyte of a redox flow battery to be recycled, the aqueous electrolyte comprising at least one electroactive compound and an aqueous solvent, the electroactive compound being at least an oxidized or reduced form of a redox couple, the oxidized form of which is a compound comprising a quinone unit, for example a benzoquinone unit, naphthoquinone unit or anthraquinone unit, preferably an anthraquinone unit, characterized in that it comprises a step (300) of precipitating the electroactive compound.
