Solvate ionic liquids (ILs) such as binary equimolar mixtures of glymes (ethyleneglycol-dimethylether or CH3(OCH2CH2)nOCH3) and lithium bis(trifluoromethylsulfonyl)amide (LiTf2N; Tf = SO2CF3) are known to show identical self-diffusion coefficients for glymes and Li+ ions. Here, we report that the addition of LiTf2N to the solvate ILs drastically changes their electrolyte properties. When the lithium salts are added to give the super-concentrated electrolytes with [O]/[Li+] = 3 (molar ratio of ether oxygen to Li+), ligand exchange or hopping conduction of Li+ takes place for triglyme (G3; n = 3) and tetraglyme (G4; n = 4). In addition, the Li+ transference number tLi+(EC), electrochem. measured under anion blocking conditions, increases about 3-6 times compared with the solvate ILs. Consequently, segmental motion of glymes apparently affects the transport properties even for the shorter G3 in the super-concentrated region. The relationship between the coordination structure and the transport properties are also discussed as a function of ionicity, the extent of the contribution of self-diffusion to the actual ion conduction. Plots vs ionicity demonstrate that a clear line can be drawn between the solvate ILs and the super-concentrated electrolytes.
