Abstract
Supercapacitors gained more attention in energy storage systems in order to improve the power density in both commercial and industrial applications. This paper deals with a study on mathematical and simulation model of an Electric Double Layer Capacitor (EDLC) based on Finite Element Modeling (FEM) in COMSOL, a Multiphysics simulation software. The simulation model studied the performance characteristics of the nanoparticle coating on the electrodes of EDLC. In addition, a graphite composite material is fabricated as electrode, where Titanium dioxide and Aluminum dioxide nanoparticles are coated separately on each pair of electrodes. The influence of high permittivity nanoparticles on the dielectric properties are investigated targeting improvement in efficiency as well as the life span of the hybrid electrical energy storage. Selection of high permittivity nanoparticle shown improvement in dielectric properties of the EDLC.
