Therefore this model investigates the aforementioned ionic liquid-solid mechanism. We also investigated the effect of volume exclusion through steric effects. Near the electrodes concentrations can get extremely high and thus volume exclusions do locally affect the microscopic double layer structure, but overall similar SSA results are found in both instances so for simplicity we present the results without steric effects here. There are other proposed SSA mechanisms that would require different physics to be investigated and are not incorporated in our current model. The pH of the system once in contact with CO2 cannot be measured experimentally due to the low volume of electrolyte. Additionally the carbon is known to adsorb
