This experiment was performed by following the similar method of Kowalski et al. Ag/Ag + . Continuous stirring was used in both working and counter electrode chambers to ensure the necessary mass transfer as well as completion of the charging-discharging cycle. The applied anodic current was 2 mA and the cathodic current was 1 mA, respectively. collected at scan rate over a range of 50-2500 mV. All the data was collected as a reduction step first followed by an oxidation step. Redox potential (E 1/2 ) of Fe III (acac) 3 was found to be -0.61 V.
