Resistivity of Mesopore Confined Solvent Free Ionic Liquid Determined by Electrochemical Impedance Spectroscopy of Ordered Porous Carbon Nanotube Supercapacitors

Abstract

Detailed analysis of electrochemical impedance spectroscopy measurements of carbon nanotube/anodized aluminum oxide/silicon supercapacitors is presented. The highly ordered structure of the AAO allows for the extraction of in-pore resistivity of ionic liquids, which is found to be 5 times greater than bulk resistivity. These pores are 24.4 + or - 4.6 nm in diameter, well into the mesopore regime and larger than other pore where increased resistivity has been reported.
