Claim 8:
9. A system for making a valence-adjusted electrolyte solution from an electrolyte solution having at least four oxidation states, the system comprising:
a reduction system that includes:
an electrochemical reduction cell designed and configured to electrochemically reduce the electrolyte solution based on a reductant;
a recirculation loop designed and configured to recirculate at least a portion of the electrolyte solution to the electrochemical reduction cell;
a reduction-process control system in operative communication with the reduction system so as to control the valence of the electrolyte solution in the reduction system to a desired value; and
an output designed, configured, and located to output the electrolyte solution as previously reduced electrolyte solution at about the desired value; and

an oxidation system that includes:
an electrochemical oxidation cell designed and configured to electrochemically oxidize the previously reduced electrolyte solution based on an oxidant;
a recirculation loop designed and configured to recirculate at least a portion of the previously reduced electrolyte solution to the electrochemical oxidation cell;
an oxidation-process control system in operative communication with the oxidation system so as to control the valence of the previously reduced electrolyte solution in the oxidation system to a desired final value; and
an output designed, configured, and located to output the previously reduced electrolyte solution at about the desired final value.
