Graphene-Based Materials for Flexible Supercapacitors

Abstract

Rapid growth of flexible/wearable electronic devices has encouraged the swift development in the direction of fabricating high performance flexible supercapacitors with superior electrochemical performance. Recently, graphene based electrodes have received a great deal of attention for flexible supercapacitors on account of their outstanding properties; including excellent mechanical flexibility, enormous surface area and high electrical conductivity. This chapter summarizes the recent research progress on flexible supercapacitors and identifies the existing challenges related to preparation of electrodes and their device fabrication with regulated electrical and electrochemical properties. Furthermore, it draws attention towards the recent flexible prototype supercapacitors, in plane supercapacitors and fiber-type supercapacitors development. Moreover, it aims for insightful understanding on opportunities and challenges, endowing stimulation of further research progress in this fascinating field.
