Recently,the electrochemical conversion of carbon dioxide(CO2)into high-value chemicals has gained significant attention.However,most studies have focused on using high-purity CO2 as the feed gas,overlooking the challenges associated with processing more readily available mixed gas streams such as air and flue gas under ambient conditions.One innovative approach addressing this gap is the supercapacitive swing absorption(SSA)technology.Powered by clean electrical energy,SSA achieves selective CO2 adsorption and desorption during the charge and discharge cycles of supercapacitors,thereby enabling the effective separation and purification of CO2 from gases of varying concentrations.SSA technology is distinguished by its operational simplicity,low energy consumption,and environmental friendliness,marking it as a viable candidate for next-generation CO2 capture and separation techniques.Despite its potential,the research about SSA is still at an early stage and is hampered by limitations such as inadequate CO2 adsorption capacity and ambiguous reaction mechanisms.These issues pose significant barriers to the commercialization and broader application of SSA technologies.This paper presents a detailed review of the recent advancements in SSA technology,including reaction mechanisms,device design,and performance metrics.It critically analyzes the factors affecting SSA performance from multiple perspectives and concludes by identifying the current challenges within SSA systems.The goal is to offer a thorough guide that will illuminate future research in this emerging area.
