Theoretical Model for Nanoporous Carbon Supercapacitors

Abstract

Importance of pore curvature: A theoretical model is proposed for nanoporous carbon supercapacitors to replace the commonly used one for an electric double-layer capacitor (EDLC) on the basis of an electric double-cylinder capacitor (EDCC) for mesopores, which becomes an electric wire-in-cylinder capacitor (EWCC) for micropores (see picture; left to right: decreasing pore size). This model explains the experimental data in various pore ranges, showing the significance of pore curvature.
