Abstract: Although great efforts have been made on development of high performance Li-ion batteries and fuel cells in the past, the slow power capability and high maintenance cost have kept them away from many applications. Recently, supercapacitors have drawn great attention because of their high charge/discharge rate, long life cycle, outstanding power density and no short circuit concern. However, supercapacitors generally exhibit low energy density. The objective of this thesis research is to develop graphene-based supercapacitors with simultaneously high power density and energy density at low production cost. Supercapacitors, also known as ultracapacitors or electrochemical capacitors, store energy as electrical charge on highly porous materials. Currently one major challenge that keeps supercapacitors from their promising applications is their low energy density. One promising electrode material candidate for electric double-layer (EDL) supercapacitors is graphene. Graphene, due to its unique lattice structure, exhibits appealing electrical properties, chemical stability and high surface area. Ideally a monolayer of sp2 bonded carbon atoms can reach a specific capacitance up to ~550 F/g as well as a high surface area of 2675 m2/g. So far, a variety of methods have been developed to synthesis graphene starting from graphite, but the cost, graphene quality and productivity remain main obstacles for their industrial application. The porous graphene material reported in this thesis was synthesized by a scalable oxidation-reduction method involving a rapid annealing process. The scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images revealed the morphology and successful exfoliation of reduced graphene oxide (rGO). The interlayer distance characterized by X-ray diffraction (XRD) is 3.64 Å (24.44°) suggesting the removal of oxygen-containing functional groups, such as carbonyl, hydroxyl and carboxyl groups. In the X-ray photoelectron spectroscopy (XPS), the C/O ratio increases from ~2 to ~5 with O1s peak reduced significantly from graphite oxide (GO) to reduced graphene oxide. Furthermore, the successful reduction was verified by the low intensities of oxygen-related peaks in Fourier transform infrared spectroscopy (FTIR). In addition, the high Brunauer-Emmett-Teller (BET) specific surface area of 410 m2/g and mesoporous structure of the synthesized material would be beneficial to the improvement of charge-storage capability and thus energy density in supercapacitors. To evaluate the electrochemical performance of graphene electrodes, supercapacitors were assembled in symmetrical cell geometry. The near rectangular cyclic voltammetry (CV) curves with EMIMBF4 and LiPF6 at scan rate of 100mV/s suggest very efficient charge transfer within the porous graphene electrodes. The triangle charge-discharge responses with a small voltage drop and vertical spike in the low frequency region of a Nyquist plot indicates an ideal capacitor performance. The specific capacitance of 306.03 F/g and energy density of 148.75 Wh/kg at 1A/g were realized with highly porous graphene electrodes. Meanwhile, the power density extracted at 8A/g reaches ~10 kW/kg, thus, making it suitable for high power applications. Compared with previously investigated carbon-based EDL capacitors, the supercapacitor based on the annealed graphene electrode is a milestone in terms of capacitance and energy density. Moreover, the supercapacitors assembled with graphene electrodes shows excellent stability for 10,000 charge-discharge cycles.

Supercapacitors have drawn intensive attention owing to their virtues of high power density, long cycle life, short charging time and safe operation for promising applications to resolve problems of limited global energy supply and environmental problems. Supercapacitors are designed to bridge the gap between batteries and capacitors, to form fast charging energy-storage devices of intermediate specific energy. The supercapacitor is an important device in the energy storage and conversion systems, and is used in different applications such as in electric vehicles, uninterruptible power supplies, memory protection of computer electronics and cellular devices.This book serves as a guide in understanding the basics of conducting polymer technology, nanostructurisation of conducting polymers and their composites emerging as a new field of research and development, directed to the creation of new smart materials, especially for supercapacitors.The concepts of supercapacitors are well explained in simple and concise form to avoid the confusion of students and academic professionals. The book has chemical engineering orientation and therefore, professionals from the polymer science field may find this book most suitable for their advanced and applied field of research. It will provide them an opportunity to learn about conducting polymers and nanocomposites, and their production and processing technology for supercapacitors. Although the attention is mainly focused on preparation of conducting polymer based binary and ternary nanocomposites and their electrochemical performances for supercapacitor application, this book will be a valuable reference for scientists, engineers, students and general readers who are interested in the investigation and exploitation of the fascinating new class of conducting polymer nanocomposites.

Supercapacitors are a relatively new energy storage system that provides higher energy density than dielectric capacitors and higher power density than batteries. They are particularly suited to applications that require energy pulses during short periods of time, e.g., seconds or tens of seconds. They are recommended for automobiles, tramways, buses, cranes, fork-lifts, wind turbines, electricity load leveling in stationary and transportation systems, etc. Despite the technological maturity of supercapacitors, there is a lack of comprehensive literature on the topic. Many high performance materials have been developed and new scientific concepts have been introduced. Taking into account the commercial interest in these systems and the new scientific and technological developments now is the ideal time to publish this book, capturing all this new knowledge. The book starts by giving an introduction to the general principles of electrochemistry, the properties of electrochemical capacitors, and electrochemical characterization techniques. Electrical double layer capacitors and pseudocapacitors are then discussed, followed by the various electrolyte systems. Modelling, manufacture of industrial capacitors, constraints, testing, and reliability as well as applications are also covered. 'Supercapacitors - Materials, Systems, and Applications' is part of the series on Materials for Sustainable Energy and Development edited by Prof. G.Q. Max Lu. The series covers advances in materials science and innovation for renewable energy, clean use of fossil energy, and greenhouse gas mitigation and associated environmental technologies.
