Temperature-Dependent Structural Breathing of Nanoconfined Ionic Liquids for Tunable Ionic Conductivity

“…Ionic liquids (ILs) have high ionic conductivity, low vapor pressure, and excellent thermal stability, making them ideal candidates for energy storage, catalysis, and electrochemistry. − However, one of the major challenges to restricting the wide use of ILs is their low ionic conductivity at low temperatures. Such low ionic conductivity of pure ILs is often due to their high viscosity and low diffusivity. ,, Our recent work found that the nanoconfinement effect of ILs within 2D materials can overcome these limitations by increasing the effective concentration of ions and reducing their mobility restrictions, thus enhancing ionic conductivity. , The nanoconfined effect is a phenomenon where the confinement of material in a nanostructure leads to changes in its properties due to the interaction between the material and the nanostructure. − The confinement of ILs results in several interesting effects, including increased density, increased ionic conductivity, and enhanced ion-pairing and structural ordering. These effects are a direct result of the strong electrostatic interactions between the charged ions and the charged surfaces of the nanochannel.…”
