This book is a comprehensive overview of the latest developments in the field of graphene-based electrochemical energy storage devices. Graphene is considered one of the most promising materials for developing high-performance electrochemical energy storage devices due to its large surface area, high electrical conductivity, and superior mechanical strength. This book highlights its fundamental properties, synthesis methods, and various electrochemical energy storage applications such as in supercapacitors, batteries, and fuel cells. The first chapter introduces the electronic, mechanical, and thermal properties of graphene and discusses various synthesis methods such as mechanical exfoliation, chemical vapor deposition, and epitaxial growth. Additionally, it describes the functionalization of graphene to enhance its characteristics for electrochemical energy storage applications. The second chapter focuses on the application of graphene in supercapacitors, energy storage devices that require high power density. It details different types of supercapacitors such as electrochemical capacitors, pseudo capacitors, and hybrid capacitors and discusses how graphene can enhance their performance. The third chapter covers the use of graphene in batteries, describing how graphene-based anodes and cathodes improve energy density, cycling stability, rate capability across various battery types including lithium-ion, sodium-ion, and zinc-ion batteries. The final chapter is dedicated to the use of graphene in fuel cells, electrochemical devices that transform chemical energy into electrical power, and describes how graphene-based materials can be utilized as catalysts or supports within fuel cells for improved performance and durability. Various types of fuel cells such as proton exchange membrane fuel cells, direct methanol fuel cells, and solid oxide fuel cells are examined. The book concludes by highlighting the future prospects and challenges in graphene-based electrochemical energy storage applications. Written in a succinct and clear manner, this book serves as a modern reference on the topic and is a valuable resource for researchers, scientists, and engineers working in the area of energy storage.

This book provides a comprehensive review of the effects of key factors ranging from powder characteristics to process parameters, substrate preparation, and post-treatment methods on the coated substrate surface by different thermal spray techniques. Thermal spray techniques have gained significant attention in various industries due to their ability to deposit protective coatings on substrates. These coatings enhance the surface properties of substrates, such as wear resistance, corrosion resistance, and thermal insulation. However, the quality and performance of the coated substrate surface are influenced by several key factors. The book discusses the influence of parameters such as powder characteristics, process parameters, substrate preparation, and post-treatment methods on the coating microstructure, adhesion, and overall performance. The review aims to contribute to a better understanding of the factors that affect the coated substrate surface and provide insights for future research and optimization of thermal spray processes.
