Fabrication and Empirical Analysis of Graphene Dispersion/ Activated Carbon on Conductive Networks in Porous Graphite Felt Supercapacitor for Fast Charging Regenerative Braking in EV

Brayden Noh

Supercapacitors are a promising candidate for regenerative braking system due to their inherent fast charging and high-current/temperature tolerance capabilities. However, most supercapacitors suffer from high weight to capacitance ratio, which averts the use of supercapacitors in regenerative braking in electric vehicles. This research proposes a new lightweight supercapacitor electrode fabrication, which consists of networking conductive layers of graphene dispersion and activated carbon in porous graphite felt using conductive ink. The composite electrode showed a specific capacitance up to 170 F g-1 or 13 F g-1 from completed device in type iii deep eutectic solvent electrolyte, which gave the starting voltage of 2.3 V. The submersion fabrication alleviated the fabrication compare to brush method and production time was reduced to under 3 minutes of physical preparation.
