Investigation on Performance of Electrochemical Supercapacitor with 3D Graphene-Based Electrodes
Abstract
This project studies the performance of a supercapacitor with graphene based electrodes. The study looks into the developed EDLC layers; the Stern and diffuse layers, definite size of ions and the variation of active materials surface area and pore size distribution. Graphene based supercapacitors were fabricated and its performance were characterized according to its components parameters. An equivalent circuit model was developed to mimic the charging/ discharging behaviour. The outcome of this project shows that graphene allows more ions to be adsorb in the Helmholtz region due to its mesopores and improves the supercapacitor energy density and power density. However, the lifecycle of the fabricated supercapacitor are affected by the thermal stress induced during charging/discharging process.
