Figure 11. (A) Complex electric modulus (M″) curves shifted to the peak maximum of the σ-process by employing the tTs principle, at a reference temperature of 203 K, for the [C₂HIm][TFSI] (grey symbols), C₂HIm][TFSI]/LiTFSI_0.2 (black symbols), EBPADMA + [C₂HIm][TFSI] (cyan symbols) and EBPADMA + [C₂HIm][TFSI]/LiTFSI_0.2 (blue symbols). (B) The shape parameter, β_KWW, of the σ-process, as a function of inverse temperature. (C) Relaxation map depicting the σ-process and the relaxation times of the structural α-process extracted from TM-DSC (circles in yellow) for the undoped electrolytes. The solid and dashed lines represent fits by the VFT equation (Eq. 5) to the temperature dependence of the σ-relaxation of the solid electrolytes and their respective bulk protic ionic liquids. The colored area indicates the cold-crystallization region. (Inset) An illustration of the gradient of viscosity that most likely takes place between the liquid and solid phases. The green (blue) color indicates the region with the lower (higher) effective medium’s viscosity. The interfacial region between the two segregated phases is indicated by dashed lines.
