In order to make a significant impact on climate change, carbon capture will likely require application at the gigaton scale. Hence any capture technique must be highly scalable. Herein, we demonstrate that SSA modules are readily scalable through the introduction of bipolar electrode stacks without a negative impact on adsorptive performance, and with a positive impact on energy consumption. The bipolar electrode design minimizes the number of current collectors which are a significant cost factor. In addition, bipolar electrodes have a lower resistance than monopolar electrodes, making them attractive from an energetic standpoint. An added benefit is that the current density is uniform at all points in a bipolar electrode. This uniform current density also eliminates voltage gradients between the tabbing points at the opposite edges of the current collectors found in monopolar electrochemical device designs, producing uniform charging, discharging, and heat generation across the entire electrode. Finally, bipolar electrode stacks allow for the compactness of the device, and space-efficiency. The SSA modules with bipolar electrode stacks described herein consist of layers of inexpensive BPL 4x6 activated carbon electrodes, cellulose-based separators, 1M aqueous NaCl as electrolyte, carbon cloth as gas conduit, and titanium foil (Figure ). The titanium foil is intersected between the positive electrodes, and the carbon cloths which are interfaced with the negative activated carbon electrodes. Together, these components constitute a bipolar electrode (Figure ). The role of the titanium foil is to prevent ion-migration between the positive and the negative "ends" of the bipolar electrode, yet providing electronic conductivity throughout the electrode. In experiments without the Ti foil, the electrode short-circuited, because the carbon cloth cannot fully prevent ionmigration. Titanium was chosen as the material because of its known high corrosion resistance in aqueous supercapacitors. The carbon cloth was placed above the "negative end" of the bipolar electrodes, analogously to the configuration of previously investigated single cell SSA modules (Figure ). The electrodes, separators, carbon cloths, and Ti foils had a central hole to allow for radial gas flow from the center to the periphery of the stack (Figure ). To enhance the uniformity of the gas flow a Teflon tubing with side holes was connected to the central hole in the negatively charged current collector plate. The full experimental details regarding the assembly of the stacks can be found in the "Experimental" section of the manuscript. To investigate performance as a function of scale systematically, we tested modules with 2, 4, 8 and 12 electrode pairs at 2V, 4V, 8V and 12V, containing 1, 3, 7, and 11 bipolar electrodes, respectively. We determined the adsorptive and energetic performance for each stack using the metrics previously developed for single cell SSA modules. BPL 4x6 activated carbon was used as electrode material because it is our benchmark material which is commercially available in large quantities. 1M NaCl was used as the electrolyte to be able to compare the performance of the stacks with that of previously investigated single cell SSA modules which used BPL carbon and 1M NaCl.
