Ionic liquids are widely used as electrolytes in electronic devices in which they are subject to nanoconfinement within nanopores or nanofilms. Because the intrinsic width of an elec. double layer is on the order of several nanometers, nanoconfinement is expected to fundamentally alter the double layer properties. Furthermore, in confined systems, a large portion of the ions are interfacial, e.g., at the electrode interface, leading to significant deviations of electrostatic screening and ion dynamics as compared to bulk properties. In this work, we systematically investigate the interference between elec. double layers for nanoconfined ionic liquids and the resulting influence on the structure, dynamics, and screening behavior. We perform mol. dynamics simulations for the ionic liquids [BMIm+][BF-4] and [BMIm+][PF-6] confined between two flat electrodes at systematic separation distances between 1.5 nm and 4.5 nm for both conducting and insulating boundary conditions. We find that while ion dynamics is expectedly slower than in the bulk (by ∼2 orders of magnitude), there is an unexpected non-linear trend with the confinement length that leads to a local maximum in dynamic rates at ∼3.5-4.5 nm confinement. We show that this nonlinear trend is due to the ion correlation that arises from the interference between opposite double layers. We further evaluate confinement effects on the ion structure and capacitance and investigate the influence of electronic polarization of the ionic liquid on the resulting properties. This systematic evaluation of the connection between electrostatic screening and structure and dynamics of ionic liquids in confined systems is important for the fundamental understanding of electrochem. supercapacitors.

In addition to this study using 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate, there are many other studies that have used 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6Reference of 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate) was used in this study.
3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6) is a member of lonic liquids. A multidisciplinary study on lonic liquids is emerging, including chemistry, materials science, chemical engineering, and environmental science. More specifically, some important fundamental viewpoints are now different from the original concepts, as insights into the nature of lonic liquids become deeper. For example, the physicochemical properties of lonic liquids are now recognized as ranging broadly from the oft quoted “nonvolatile, non-flammable, and air and water stable” to those that are distinctly volatile, flammable, and unstable.
