a An electrosorption-desorption cycle of PUCC at 0.1 mA cm−2. b FESEM image and corresponding elemental mappings of PUCC anode after the electrosorption process. c The electrosorption-desorption process for two devices connected in series. d A LED panel can be lighted by a CDI cell during the ion desorption process. e Cycling stability of PUCC. The insets in (e) show the CO2 adsorption/desorption isotherms and resistivity of PUCC after the cycle test.
