This review offers a carbon-centered perspective on electrochemical supercapacitive swing adsorption (SSA) for CO2 capture, where porous carbon electrodes govern charge storage, ion transport, and interfacial CO2 enrichment. It traces electrode evolution from commercial to tailored porous carbons, quinone-functionalized carbons, and COF composites, deriving structure-performance relationships linking surface area, pore architecture, and surface chemistry to capture capacity, kinetics, and energy use. Key challenges in mechanism, device design, realistic testing, CO2 utilization, and techno-economic/LCA analysis are outlined.

日本のGX文脈において
日本はCCUSをGX推進戦略の柱とし、分離回収技術の低エネルギー化は重要課題。本レビューは材料設計指針を提供し、国内の炭素材料メーカーや研究機関の技術開発に資する。ただし開示・政策文脈との直接接続は弱い。
In the global GX context
Electrochemical CO2 capture is gaining attention in global decarbonization portfolios as a low-energy alternative to amine scrubbing, relevant to CCUS hubs and hard-to-abate sectors. This review contributes materials-level design principles that inform scalability and TEA/LCA debates, though it sits upstream of disclosure frameworks like TCFD/ISSB.

📄 Abstract(原文)
Abstract Electrochemical supercapacitive swing adsorption (SSA) is an emerging CO2 capture technology that couples reversible charge storage with electrically driven CO2 uptake and release, offering the potential for low-energy operation. Porous carbon electrodes are central to SSA because they govern charge storage, ion adsorption and transport, and interfacial CO2 enrichment, thereby determining capture performance. However, the relationships between carbon structure, interfacial electrochemistry, and CO2-capture mechanisms remain poorly understood. This Review provides a carbon-centered perspective on SSA. We first summarize the fundamentals of SSA, including cell configurations, electrode materials, and proposed capture mechanisms. Particular emphasis is placed on the evolution of carbon electrodes from commercial porous carbons to tailored porous carbons, quinone-functionalized carbons, and covalent-organic-framework-based composites. We then discuss emerging structure–performance relationships, focusing on how surface area, pore architecture, and surface chemistry influence CO2 capture capacity, kinetics, and energy consumption, and derive empirical design principles for SSA electrodes. Finally, we highlight key challenges and opportunities in mechanistic understanding, material and device design, evaluation under realistic conditions, integration of CO2 capture with utilization, and techno-economic analysis and life-cycle assessment. By linking carbon structure to interfacial processes and device-level performance, this Review provides a framework for the rational design of scalable SSA systems for electrochemical carbon capture.
