In Figure we show the cell voltage vs. time starting with 100% DHA at t=0. DHA oxidation commences at approximately 0.2 hr and ends at 1.0 hr. Next, the cell is held at open-circuit for the second hour, and then put through another negolyte oxidation step at a very low cell voltage (-0.1V) during hours 2-5. Finally, the last three hours are devoted to cycling with voltage and current cutoff values appropriate for DHAQ, to evaluate the discharge capacity attributable to the DHAQ formed from DHA. The amount of DHAQ, reckoned from the accessed discharge capacity, is compared to the theoretical amount that may possibly form from the initial DHA, and their ratio reported in Figure .
