الوصف: In this article, we perform all-atom molecular dynamics simulations to investigate the structure and intermolecular interactions of Na + ions in water-in-ionic liquids. We have considered two ionic liquid systems with the same cation and different anions as (1) 1-benzyl-3-methyl imidazolium [ZMIM + ] tetrafluoroborate [BF – 4 ] and (2) [ZMIM + ] hexafluorophosphate [PF 6 – ]. We have analyzed the inter-molecular structure and dynamics of Na + ions in the ionic liquid electrolyte with an increase in water (H 2 O) mole fraction ( x ) ranging from 0.33 to 0.71. The neat ionic liquid [ZMIM + ]­[BF 4 – ] and [ZMIM + ]­[PF 6 – ] coordination structure shows a decrease, with an increase in x . We have observed that Na + ions show significant interaction with ionic liquid [ZMIM + ]­[PF 6 – ] when compared to [ZMIM + ]­[BF 4 – ] over the entire range of x considered. The coordination structure of Na + –[PF 6 – ] is more significant when compared to the coordination structure between Na + and [ZMIM + ]. The Na + ions coordinated more with H 2 O and showed a higher intensities in the presence of [ZMIM + ]­[PF 6 – ] when compared to [ZMIM + ]­[BF 4 – ]. The diffusion of Na + ions showed an increase in both the electrolyte solutions with the rise in x . The faster diffusion of Na + is seen in the presence of [ZMIM + ] [BF 4 – ]. The ionic conductivity of ionic liquids is higher for [ZMIM + ]­[BF 4 – ] when compared to [ZMIM + ]­[PF 6 – ]. Overall, this article provides detailed molecular-level insights into Na + ions in the presence of water in ionic liquids.
