Fig. 2. Physical characteristics of viscoelastic liquid electrolytes.

Fig. 2

(A) Frequency-dependent dynamic storage G′ (filled symbols) and loss G″ (open symbol) moduli for PMMA–EC/PC (v/v, 1:1)–1 M LiTFSI electrolytes as a function of polymer concentration. (B) Concentration regimes of zero shear viscosity and conductivity at 25°C. (C) Extended stability regime (from Fig. 1A) in viscoelastic electrolytes as a function of electrolyte viscosity. The dashed line through the data shows that the experimental data can be approximated by the scaling relation, ΔV : η1/4. (D) DC ionic conductivity of the viscoelastic liquid electrolytes as a function of temperature. The solid lines are Vogel-Fulcher-Tammann fits for the temperature-dependent ionic conductivity. (E) Nyquist plot obtained from EIS measurements in electrolytes with different polymer concentrations. The solid lines are fitted by an equivalent electrical circuit model shown in the supporting information (fig. S7). (F) Polymer contribution to the ASR of an electrolyte/Li interface as a function of electrolyte viscosity. The dashed line through the data shows that the experimental data obey an approximate scaling relation, Rint3 : η1/4.
