Figure 4. (A) Electrolyte uptake and (B) electrolyte retention of the PE, AM-CTF-PE and HC-CTF-PE separators; (C) EIS plots of the PE, AM-CTF-PE and HC-CTF-PE separators, the inset shows enlarged EIS plots in the high-frequency region; Chronoamperometry profiles of (D) AM-CTF-PE and (E) HC-CTF-PE separators. Inset of (D) is the AC impedance spectra before polarization, and inset of (E) is the AC impedance spectra after polarization; (F) Fitting and evaluation of activation energy using the Nyquist plots.
