a Schematic diagram of the structure and working principle of the polyviologen|Zn mesh EESD. b Corresponding SEM images of the electrolyte-coated zinc mesh and the cross-section of EESD. c The chemical structure of polyviologen and its redox mechanism. d Cyclic voltammetry curves of the polyviologen|Zn mesh EESDs with and without PEDOT:PSS at different scan rates. e Cyclic voltammetry curves of the polyviologen|Zn mesh EESDs with and without PEDOT:PSS at a scan rate of 2 mV s−1. f Linear plots of Ipa and Ipc versus the square root of applied voltage from cyclic voltammetry tests. g Calculation of b value from anodic and cathodic peaks of cyclic voltammetry tests. h Percentage of the capacitive contribution of the polyviologen|Zn mesh EESDs with and without PEDOT:PSS at different scan rates. i Nyquist plots of the two kinds of EESDs (the inset shows the corresponding fitted circuit).
