Figure 1.2: Electrochemical sketch of discharge with the all-vanadium couples. distinct color. This allows for easy visual inspection of an electrolyte’s approximate state of charge (SoC is the percent of charged ions in a solution). A disadvantage of the vanadium couples is that V(II) ions are susceptible to oxidation from oxygen in the atmosphere [4]. This degradation does change the system’s net charge and is irreversible. Figure 1.3: The four oxidation states of vanadium. 1.4 Design Considerations Flow battery designs largely resemble those of fuel cells. However, since no gases are present among the reactants, a 3-phase contact is reduced to a 2-phase contact between electrolyte and electrode. Some experimenters have implemented flow fields 4
