Carbon And Metal Oxides Based Nanomaterials For Flexible High Performance Asymmetric Supercapacitors

This thesis examines electrode materials such as mesoporous carbons, manganese oxides, iron oxides and their nanohybrids with graphene. It also explores several of the key scientific issues that act as the governing principles for future development of supercapacitors, which are a promising class of high-efficiency energy storage devices for tackling a key aspect of the energy crisis. However, critical technical issues, such as the low energy density and reliability, need to be addressed before they can be extended to a wide range of applications with much improved performance. Currently available material candidates for the electrodes all have their disadvantages, such as a low specific capacitance or poor conductivity for transition metal oxide/hydroxide-based materials. This thesis addresses these important issues, and develops a high-performance, flexible asymmetric supercapacitor with manganese oxides/reduced graphene oxide as the positive electrode and iron oxide/reduced graphene oxide as the anode, which delivers a high energy density of 0.056 Wh cm-3.

The 21 chapters in this book presents a comprehensive overview of flexible supercapacitors using engineering nanoarchitectures mediated by functional nanomaterials and polymers as electrodes, electrolytes, and separators, etc. for advanced energy applications. The various aspects of flexible supercapacitors, including capacitor electrochemistry, evaluating parameters, operating conditions, characterization techniques, different types of electrodes, electrolytes, and flexible substrates are covered. This is probably the first book of its type which systematically describes the recent developments and progress in flexible supercapacitor technology, and will be very helpful for generating new and innovative ideas in the field of energy storage material for wearable/flexible industry applications.

This book commemorates the “Nobel Laureate Professor Suzuki Special Symposium” at the International Union of Material Research Society–International Conference on Advanced Materials (IUMRS-ICAM2017), which was held at Kyoto University, Japan, in 2017. The book begins with a foreword by Professor Akira Suzuki. Subsequently, many authors who attended the special symposium describe the latest scientific advances in the field of carbon materials and carbon nanomaterials including polymers, carbon nanocomposites, and graphene. Carbon-based materials have recently been the focus of considerable attention, given their wide range of potential applications. Fittingly, the chapters in this book cover both experimental and theoretical approaches in several categories of carbon-related materials.
