However, the properties of the electrode contribute significantly to flow battery system polarization, through not only ohmic resistance but also the charge transfer polarization, because the redox reactions take place in the close proximity to the electrode surface. , 2013a). An impedance study confirmed that the addition of bismuth nanoparticles to the electrode surface lowered the charge transfer resistance and therefore reduced the cell polarization. 33), where n is the number of moles of a specified electroactive material involved in the cell reaction.

At these high storage capacities, of the different battery technologies available flow batteries offer the lowest cost per kWh capital and lowest operating costs (SkyllasKazacos, 2010). , 2006). In battery arrays, cell imbalance and reversal can occur, and lead-acid batteries require regular boost charging to maintain cell balance. Cell imbalance can be a problem for any battery array employing static (non-flow) battery cells. Deep battery discharge cycling is normally required for battery systems used for energy storage, and as lead-acid batteries rely on solid-state processes during cycling deep discharge of these batteries leads to relatively short life cycles.

In a flow cell, polarization arises from different parts of the system, including mainly kinetic polarization at the electrolyte-electrode interface, ohmic loss from the membrane, electrolyte, and electrode, and concentration polarization from mass transport limitations. As an example, the porous electrode used in a flow battery cell is sometimes referred to as a “nonparticipating electrode” due to the fact that the energy containing redox active materials is contained in the electrolyte instead of the electrode.
