Resistance and redox activity.
(a), Electrochemical impedance spectra in the form of a Nyquist plot of the DTP-ANDI-COF (dotted black curve) and DTP-ANDI-COF@CNTs (red curve) batteries tested from 10 kHz to 10 mHz. (b), CV curves of the DTP-ANDI-COF (black curve), DTP-ANDI-COF@CNTs (red curve) and COF-5 (dotted black curve) batteries tested at 0.5 mV s−1.
