Further study of this process is beyond the scope of this work and is the subject of an on-going study in our lab. When the crossover rates at rest are compared to those during constant-current discharge of the battery, no significant difference is observed (see Figure ). Migration is expected to operate in the opposite direction during discharge as the polarity of the cell is reversed. However, owing to the significantly lower concentration of 2,6-DHAQ in the catholyte ([2,6-DHAQ] <2 mM), this effect is overshadowed by the diffusional flux of 2,6-DHAQ into the catholyte from the anolyte side ([2,6-DHAQ] ~100 mM). We therefore conclude that for this system the constant-current charging step is the most influential on 2,6-DHAQ crossover.
