In Figure , we compare experimental data from various sources (including our own data) with computed Einstein-Helfand conductivities σ EH as a function of the mixture composition for two selected temperatures: 303 K and 343 K. Note that the experimentally observed behaviour is nearly quantitatively reproduced for compositions with x([Li][NTf 2 ])≥ 0.4 for both temperatures. For lower salt concentrations, the data deviate from one another, however, the data never differ by more than a factor of 2. The most prominent feature of the data shown in Figure is the presence of a maximum of the ionic conductivity around x([Li][NTf 2 ])≈ 0.2. The presence of such a maximum is due to two competing effects: with increasing G3 content, the mobility (diffusion coefficients) of the charge carriers (ions) increases significantly. This is, however, overcompensated by the dilution of charge carriers at low salt concentrations. Of course, increasing the temperatures leads to overall larger ionic conductivities due to an increasing mobility of the ions. However, as can be inferred from Figure in the SI, the balance between mobility and dilution effects is apparently also temperaturedependent, which leads to a shift of the maximum to slightly larger values with increasing temperature.
