(a) Nyquist plots of the ILPE membranes with different EMITf contents measured at ambient temperature and corresponding equivalent circuit (CPE = constant phase element, Rb = resistor, and Cdl = double-layer capacitor). (b) Variation of ambient temperature ionic conductivity with the mass ratio of EMTIf to PVdF-HFP. (c) DC polarization curve of ILPE-Zn-4 membrane under 0.5 V at room temperature. (d) The ILPE-Zn-4 membrane used as an ionic conductor to successfully connect the LED circuit.
