The ionic conductivity of LiBOB-doped electrolytes containing two silyl solvents, bis[2-(2-methoxyethoxy)ethoxy] dimethylsilane, 1, and [2-(2-methoxyethoxy)ethoxy] trimethylsilane,2, was measured from −10 °C to 50 °C using AC impedance spectroscopy to assess their potential use in commercial Li-ion cells. The effects of salt concentration, solvent composition, and temperature on the conductivity of the electrolytes are reported. In addition, conductivity data were fit using the Vogel-Tamman-Fulcher (VTF) equation to obtain the parameters σ 0, T 0, and E a , which correspond closely to conductivity and viscosity. All the electrolytes produced conductivities above the 1.0 mS cm−1 threshold required for commercial application. The 1:1 (vl) solvent composition possesses the highest conductivity, with the optimal 0.8 M salt-loading yielding the highest σ 25 at 1.99 ± 0.02 mS cm−1.
