Carbon capture is a promising technology to mitigate greenhouse gas emissions to achieve net carbon neutrality. Electro‐swing reactive adsorption has emerged as an attractive approach for sustainable decarbonization. However, current electrodes with limited gas transport present a major barrier that hinders their practical implementation. Herein, porous polymeric electrodes are developed to effectively enhance CO2 transport without the need for additional gas diffusion conduits. Such all‐in‐one porous electrodes also enable more accessible redox active sites (e.g., quinones) for CO2 sorption, leading to an increased materials utilization efficiency of ≈90%. A continuous flow‐through carbon capture and release operation with high Faradaic efficiency and excellent stability under practical working conditions is further demonstrated. Together with low cost and robust mechanical properties, the as‐developed porous polymeric electrodes highlight the potential to advance the future implementation of electrochemical separation technologies.
