Electrolyte was held in polypropylene plastic centrifuge tubes with 15 mL of headspace. Electrolyte was deaerated with argon for 1 h prior to experiment onset and an argon blanket was maintained over the electrolyte during experiments. The flow rate was set to 10 ml/min for all experiments. 1.2 Electrolyte Composition The electrolyte composition was based on the work done by Kim et al.8 5 M HCl was produced from a 37% concentration source solution from Sigma-Aldrich diluted in DI water. Reagent grade VOSO4 from Sigma-Aldrich was added to the HCl solution so that the SO4 and V concentration reached 2.5 M. Electrolyte was mixed overnight using a magnetic stir bar to fully dissolve the vanadium. Initial charging to bring the electrolyte to the desired valence states was done by adding 2x the volume of the negolyte to the posolyte vial (30 mL posolyte, 15 mL negolyte). Then the cell was charged to a voltage of 1.7 V at a current of 25 mA/cm2 and a flow rate of 10 ml/min. The excess posolyte was removed to balance the volumes of each side of the battery, leaving 15 mL of each solution. 1.3 Cell Cycling Constructed full cells were cycled using a Solartron 1278A Potentiostat or a Biologic SP 150 potentiostat. The Solartron system was used in experiments where there was no reference electrode, and the Biologic system was used for experiments with a Pt pseudo reference electrode. All cycling was done at room temperature. All experiments shown in the main body of the paper were done on one cell build. The system was allowed to rest for a minimum of 2 hours at 0% SOC between experiments. 18PDF Image | Chlorine Gas Generation in Mixed-Acid Vanadium Redox
