Preface

Supercapacitors are a new class of superior energy storage devices that provide both high energy and power densities, bridging the gap between batteries and regular capacitors. The two primary charge storage processes of supercapacitors are the redox process and the electrochemical double layer. Considerable interest is being paid to strategies that would combine both mechanisms in a supercapacitor to improve its electrochemical characteristics. The energy storage capacity of supercapacitors can be greatly impacted by the electrode materials utilized to make these devices. For supercapacitors, a variety of materials are being used, including conducting polymers, carbon-based materials, layered structured materials, metal oxides, and sulfides. The energy and power density of supercapacitors might vary depending on the materials' shape and kind. This book discusses developments in next-generation supercapacitor materials such as Mxene, MOFs, Quantum dots, and graphene-based nanostructures. A brief history of nanostructural materials, chemistry and supercapacitors as energy storage devices is also provided. This technical book can be a very helpful reference for scientists, industrial practitioners, graduate and undergraduate students, and other professionals in the scientific and education domains.

This book attempts to present the most recent as well as future forming materials, and ground-breaking developments in nanostructured materials for supercapacitor applications. The numerous intriguing characteristics of nanoscale materials make them perfect for energy storage applications. Additionally, methods are used to improve their morphological, electronic, and electrical characteristics in order to improve their electrochemical performances. Numerous new nanocomposites based on Mxenes, MOFs, Quantum dots, and variants of graphene are discussed. In-depth descriptions of novel methods for synthesizing and customizing their electrochemical characteristics are provided. With thorough characterization, mechanistic techniques, and theoretical analysis, this book compiles information on the production and applications of nanomaterials for supercapacitors. Recent advances in cutting-edge technology, including flexible and wearable supercapacitors made of nanostructured materials, are discussed. The readers of this book are given both basic and specialized techniques for creating nanostructured materials for supercapacitors.
