Modern ionic liquids (ILs) are magical green solvents for the future due to their inherited advantages and remarkable transport properties. One of the ubiquitous properties in ILs is the intrinsic ionic conductivity. However, the understanding of super-Arrhenius behavior of ionic conductivity process at elevated pressure still remains elusive and crux in glass science. In this work, we investigate the ion transport properties of 1-butyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide: [C4mim] [NTf2], 1-butylimidazolium bis[(trifluoromethyl)-sulfonyl]imide: [C4Him] [NTf2] and 1-butylimidazolium hydrogen sulfate: [C4Him] [HSO4] ILs in supercooled liquid state using dielectric spectroscopy at ambient and high pressure. We present the experimental data in the dynamic window of conductivity formalism to examine the charge transport properties. The frequency-dependent ionic conductivity data have been analyzed using the time-temperature superposition principle. In the Arrhenius diagram, thermal evolution dc-conductivity reveals similar temperature dependence for both protic and aprotic ILs thus making it difficult to distinguish the ion dynamics. However, our results demonstrate the key role of high pressure that unambiguously separates the charge transport properties of protic ILs from aprotic ones through apparent activation volume paramterer. We also highlight that the activation volume can be employed to assess the information connecting the ability of ionic systems to form H-bond networks and the impact of proton transfer involved in the conduction process.
