1. A flow battery comprising:

  • a first aqueous electrolyte comprising a first redox active material;

    a second aqueous electrolyte comprising a second redox active material;

    a first electrode in contact with said first aqueous electrolyte;

    a second electrode in contact with said second aqueous electrolyte and a separator disposed between said first aqueous electrolyte and said second aqueous electrolyte;

    said flow battery having an open circuit potential of at least about 1.4 V and being capable of operating or are operating at a current density of at least 50 mA/cm2; and

    wherein both of the first and second redox active materials remain soluble in both the charged and discharged states.
