At mixing ratios of x([Li][NTf 2 ]) = 0.4 to 0.5, all cations and G3 molecules are, on average, involved in forming complexes with each other. The cations and their enclosing G3 molecules move jointly, resulting in almost equal selfdiffusion coefficients for both components. This is clarified in Figure , highlighting the ratios of the self-diffusion coefficients of [Li] + and G3.
