Chemical Routes to Graphene-Based
Flexible Electrodes for Electrochemical
Energy Storage
Fei Liu and Dongfeng Xue
Abstract Due to their many fascinating properties and low-cost preparation by
chemical reduction method, particular attention has been paid to the graphene-based
materials in the application of energy storage devices. In the present chapter, we
focus on the latest work regarding the development of flexible electrodes for bat-
teries and supercapacitors based on graphene as well as graphene-based composites.
To begin with, graphene as the sole or dominant part of flexible electrode will be
discussed, involving its structure, relationship between structure and performance,
and strategies to improve their performances; The next major section deals with
graphene as conductive matrix for flexible electrode, the role of graphene to offer
efficient electrically conductive channels and flexible mechanical supports will be
discussed. Another role of graphene in flexible electrode is as active additives to
improve the performance of cellulose and carbon nanofiber papers, examples will be
given and such strategy is promising for further reducing the cost of flexible elec-
trodes. Finally, prospects and further developments in this exciting field of graph-
ene-based flexible energy storage devices will be also suggested.

1 Introduction
There has been an increasing interest recently in soft or bendable portable elec-
tronic equipment, such as roll-up displays, wearable devices and implanted
medical devices, to meet the various requirements of advanced applications [ 1 - 4 ].
