Abstract: The present invention relates to an aqueous energy storage system, comprising a half-cell containing an aqueous solution of at least two redox-active compounds (RACs) and one or more insoluble preferably organic energy storage material(s). Moreover, the use of such a half-cell as negative electrode in redox-flow battery application is described.

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.
