It is clearly visible that the shifting ability of the whole resulting CV curve of the W-Cap is significantly decreased when negative (Figure ) or positive (Figure ) Ubias are applied in comparison with the system where activated carbon (Cmeso) is used as GE material. As the potential distribution of WE, CE, and GE reveal, the GE electrode (Ti-mesh) as highly polarizable material with low areal capacitance is mainly shifted upon biasing to more negative (when negative Ubias is applied) or positive (positive Ubias) potentials. Consequently, the potentials of W-Cap electrodes are only slightly shifted; the larger the surface area ratio GE:CE, the more significant the shift in the potential of the W-Cap electrodes. Furthermore, almost no current/capacitance increase of the W-Cap is observed (Figure ) when Ubias is applied due to the fact that the Ti-mesh has a very low areal capacitance and cannot cause a significant capacitance increase of the CE. Therefore, despite the small shift (much lower compared to the carbon-based GE) of the WE and CE potential range towards higher values to the anion adsorption region, Ti-mesh cannot fully balance the charge through cations adsorption on its surface due to its limited surface area.
