1. A method for determining upper and/or lower limits of convection in a flow cell battery, the method comprising:

circulating a single electrolyte comprising an electroactive species in an electrochemical cell comprising a positive electrode, a separator, a negative electrode, wherein the electromigrative flux of the electroactive species is greater than the sum of the diffusive flux of the electroactive species and the convective flux of the electrolyte;

applying a voltage between the positive electrode and the negative electrode to generate an electromigrative flux of the electroactive species; and

circulating the single electrolyte in the electrochemical cell, wherein the electromigrative flux of the electroactive species is less than a sum of the diffusive flux of the electroactive species and the convective flux of the electrolyte.
