Figure 4. (A) DSC thermograms of the EBPADMA + [C₂HIm][TFSI]/LiTFSI electrolytes (blue) and their corresponding liquid electrolytes [C₂HIm][TFSI]/LiTFSI (black), with a Li-salt concentration equal to either 0.0 m (dashed lines) or 0.2 m (solid lines). The DSC traces shown are those recorded during the second heating at a rate of 10 K/min. The thermograms are vertically offset for clarity. (B) Reversing heat capacity as a function of temperature for samples [C₂HIm][TFSI]/LiTFSI_0.2 (black) and EBPADMA + [C₂HIm][TFSI]/LiTFSI_0.2 (blue), by employing TM-DSC with a period of 200 s and a linear heating rate of 0.5 K/min. Li-salt concentration dependence of (C) the crystallization and melting temperatures, (D) the enthalpy of fusion, and (E) the liquid-to-glass temperature, estimated from TM-DSC measurements (P = 200 s, β = 0.5 K/min) for the bulk liquid phase (black symbols) and the liquid phase inside the polymer (blue symbols). The arrows guide through the effect of increasing the Li-salt content (green arrows) and confinement (orange arrows). (C-E) The lines are simple guides to the eyes.
