SSA modules with bipolar electrode stacks having 2, 4, 8 and 12 electrode pairs were successfully tested. The maximum voltage can be increased proportionally with the number of electrode pairs in the stack to 2, 4, 8, and 12 V, respectively without loss of capacitive behavior. The sorption capacity (~58 mmol•kg -1 ) and the adsorption rates (~38 µmol•kg -1 •s -1 ) remain constant for all stacks demonstrating scalability. Also, the coulombic efficiency (~97%), specific capacitance (~77 F•g -1 ) and electron efficiency (~0.14 molecules CO2•electron -1 ) are similar for all investigated stacks. The productivity scales with the number of electrode pairs. The scaling strategy significantly decreases the resistance and energy loss per cell, which substantially increases energy efficiency and reduces energy consumption. For a 12-cell stack, the energy consumption is reduced to 60 kJ•mol -1 compared to 142 kJ•mol -1 for a 2-cell stack, and 202 kJ•mol -1 for a single cell. The results suggests that energy consumption will likely further decrease with additional scaling. Further improvements could be made by the replacement of the relatively expensive titanium foil, by cheaper alternatives, for example carbon black-infused polyethylene films which recently proved effective in aqueous ZnBr2 battery stacks with bipolar electrodes. In addition, gas flow channels could be imprinted into the electrodes, eliminating the need of the relatively expensive carbon cloth a gas conduit. Sorption capacity could be increased by the replacement of BPL carbon with garlic-root derived carbon and NaCl by MgBr2 electrolytes, which performed significantly better in previous single cell experiments. We also recently demonstrated that warm-pressing the electrodes significantly increases sorption capacity, and reduces energy consumption in single cell SSA modules, suggesting that scaled SSA modules with bipolar electrode stacks can be further improved by using warm-pressed electrodes. Research into these directions is currently underway in our laboratory.
