Abstract
We report a scaled-up supercapacitive swing adsorption (SSA) module with a novel radial gas flow design to separate CO2 from a simulated flue gas mixture containing 15% CO2 and 85% N2. We define metrics that allow for a quantitative evaluation of the energetic and adsorption performance of SSA cycles, namely, the specific capacitance, the Coulombic efficiency, the energy efficiency, the energy loss, the sorption capacity, the electron efficiency, the energy consumption, the adsorption rate, and the time-energy efficiency. Using these metrics, we investigate the influence of different electrical charge
