Graphene-based supercapacitor: Fabrication and their properties
Jin-Gang Yu
As one-atom thick layer with two-dimensional (2D) architecture, graphene has emerged as an efficient capacitor electrode material for electrochemical energy storage due to its excellent properties such as high electrical conductivity, superior chemical stability, and extensive surface area. However, graphene tends to aggregate when prepared by the chemical reduction method due to the inter-sheets van der Waals interaction. To prevent the aggregation of graphene and improve its electrochemical performance, various materials such as metal compounds, polymers, and carbonaceous materials were doped into graphene to fabricate novel graphene-based hybrids, which showed excellent capacitive properties and high stability. Therefore, these graphene-based supercapacitor electrode materials are hoped to have great prospect as future supercapacitors.
