    Abstract: The present invention provides a process for the regeneration of an aqueous electrolyte solution of a redox-flow battery containing at least one inorganic redox active compound, said process comprising at least one of the following steps (a), (b) and/or (c): (a) treatment of the electrolyte solution in order reduce the at least one inorganic redox active compound to the reduced state; (b) removal of precipitated material from the electrolyte solution and subsequent modification of the precipitated material to obtain at least one water soluble inorganic redox active compound; and/or (c) separation of inorganic redox active compounds from redox active compounds other than the at least one inorganic redox active compound.
