Graphene Nano Composites for High Performance Super Capacitor

Abstract

Graphene-based nano composites have shown great promise as a material to improve the effectiveness of super capacitors because of its special combination of mechanical flexibility, chemical stability, high surface area, and superior electrical conductivity. An overview of current developments in the design and manufacturing of graphene nano materials for efficient super capacitor applications is given in this article. The effects of different synthesis techniques, including chemically vaporized depositing, also hydrothermal synthesizing, and electrochemical deposition, on the shape and characteristics of the final nano composites are examined. Additionally, the impact of several graphene fillers on the electrochemical stability of super capacitors is examined, including reduced graphene oxide, the material graphene oxide, and the nano sheets of graphene. Methods such as surface functionalization, electrode architecture optimization, and hybridized with other nano materials are also highlighted as ways to enhance the density of energy, power density, and stability during cycling by incorporating graphene the nano composite materials into super capacitor electrodes. All things considered, graphene-based nano composites have a great deal of promise to enable super capacitors to operate at higher efficiency, opening the door for their wider commercialization in a range of energy conversion and storage applications.
