Electrode Interface

The role of the electrode material on the interfacial double layer structure of a series of ionic liquids comprising 1-butyl-3-methylimidazolium hexafluorophosphate (C4MIM][PF6]), 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C4MIM][Tf2N]) and 1-butyl-3-methylimidazolium tetrafluoroborate ([C4MIM][BF4]) was investigated on gold (Au) and platinum (Pt) electrodes.

<div>In this article we discuss the nanostructure and calculated the capacitance of a solvate ionic liquid–electrode interfaces, where the electrode has a constant potential, and is thus inherently polarisable. Lithium ions from the lithium</div><div>glyme solvate ionic liquid are found within 0.5 nm of the electrode at all voltages studied, however, their solvation environment varies with voltage. Our study provides molecular insight into the electrode interface of solvate ionic liquids, with many features similar to pure ionic liquids. A comparison with previous studies of the same electrolyte using the fixed surface charge boundary condition is also illuminating, informing future computational studies of electrolyte–electrode interfaces.</div>
