摘要

Background: A tremendous amount of research work has been done over the past decade toexplore the potential of graphene for energy applications including its use in supercapacitors because ofits unique characteristics such as: novel charge transport behavior, superior electrical and thermal conductivity,good chemical stability, outstanding mechanical behavior, and above all its tunable interlayerspacing. A variety of ions has intercalated into the graphene layers without damaging its structure suggestingstructural stability and durability for energy storage applications. Although the energy storagecapacity of pure graphene is low, its charge storage capacity can be improved by synthesizing nanocompositesof graphene with polymers, metal oxides, and carbon-based materials. Nanocomposites withconducting polymers such as polyaniline, polypyrrole and polythiophenes can provide various nanostructureswith improved electrochemical properties compared to pure graphene and conducting polymers.On the other hand, metal oxides provide ultra-high faradic capacitive performance and othercarbonbased materials help in creating complex nano-structural morphology for enhanced energy storagecapacity.Objective: The purpose of this review article is to provide both a comprehensive and critical scientificprogress that has so far been made on nanocomposites of graphene. We will especially focus on topicssuch as the supercapacitive performance in terms of specific capacitance, energy density, power density,cycling life, rate capability and the working principles of supercapacitive nanocomposites.
