Quantum Energy Storage in Dielectric<Ionic Liquid> Porous Clathrates

Abstract

The current work represents results for the encapsulation of 1-Allyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ionic liquid (IL) in the cavities of the SBA-15 mesoporous dielectric matrix for the first time to our knowledge. Obtained SBA-15 clathrate is a structure with a nanodimensional phase of IL matrix-ordered and isolated by dielectric SiO2. The character of frequency dependent impedance, loss tangent, and dielectric constant for obtained clathrate was investigated under normal conditions, under illumination, and in constant magnetic field. Current-voltage characterisation revealed the capacitive properties of the obtained nanohybrid structure and Cole-Cole diagrams confirmed the Jonscher mechanism of charge relaxation in it. The conditions of the synthesised SBA-15 accumulating the electric energy at a quantum level were determined. The results presented in this work are unique and they prove that the synthesised substance is promising for application in quantum accumulators.
