Book Description
This volume reviews the preparation, structures, physicochemical properties and applications of graphite fluorides, mainly based on the results obtained by the authors. Their interest in graphite fluorides stemmed from research on the ``anode effect'', in electrolytic production of fluorine gas in KF.2HF melt using carbon electrodes. The formation of a thin graphite fluoride film on carbon anodes made it difficult to continue the electrolysis of KF.2HF at a high current density. To elucidate this phenomenon studies on graphite fluoride were initiated. In the course of these systematic studies, the use of graphite fluoride in high-energy batteries became successful: a new graphite fluoride (C2F)n was found; and another fluorineographite intercalation compound with ionic bonding, CxF, was synthesized. During this research it was established that CxF is closely associated with the ``anode effect''. The book will be of interest to all those involved in the study and research of graphite fluorides, particularly fluorine chemists, electrochemists, and fluorine and battery companies.

Book Description
Inorganic Solid Fluorides: Chemistry and Physics deals with the chemical and physical properties of inorganic solid fluorides and covers topics ranging from methods used in the preparation of fluorides to the crystal chemistry of fluorides and transition metal oxyfluorides. Defects in solid fluorides are also discussed, along with fluorine intercalation compounds of graphite and high oxidation states in fluorine chemistry. This book is comprised of 21 chapters and begins with an overview of general trends related to fluorides, including bonding problems and economic implications of fluorides. Some of the methods for the synthesis of inorganic solid fluorides are then described, including gas-phase reactions, reactions in solution, gas-solid reactions, and partial or all solid-state reactions. Subsequent chapters explore the properties of fluoride glasses; ferromagnetism and ferrimagnetism in fluorides; competing spin interactions and frustration effects in fluorides; and electronic conduction in fluorides. Fast fluorine ion conductors and nonlinear properties of fluorides are also considered. The final chapter is devoted to industrial uses of inorganic fluorides. This monograph should be of interest to physicists and inorganic chemists as well as students of physics and inorganic chemistry.

Book Description
This book summarizes recent progresses in inorganic fluorine chemistry. Highlights include new aspects of inorganic fluorine chemistry, such as new synthetic methods, structures of new fluorides and oxide fluorides, their physical and chemical properties, fluoride catalysts, surface modifications of inorganic materials by fluorination process, new energy conversion materials and industrial applications. Fluorine has quite unique properties (highest electronegativity; very small polarizability). In fact, fluorine is so reactive that it forms fluorides with all elements except with the lightest noble gases helium, neon and argon. Originally, due to its high reactivity, fluoride chemistry faced many technical difficulties and remained undeveloped for many years. Now, however, a large number of fluorine-containing materials are currently produced for practical uses on an industrial scale and their applications are rapidly extending to many fields. Syntheses and structure analyses of thermodynamically unstable high-oxidation-state fluorides have greatly contributed to inorganic chemistry in this decade. Fluoride catalysts and surface modifications using fluorine are developing a new field of fluorine chemistry and will enable new syntheses of various compounds. The research on inorganic fluorides is now contributing to many chemical energy conversion processes such as lithium batteries. Furthermore, new theoretical approaches to determining the electronic structures of fluorine compounds are also progressing. On the industrial front, the use of inorganic fluorine compounds is constantly increasing, for example, in semi-conductor industry. "Advanced Inorganic Fluorides: Synthesis, Characterization and Applications" focuses on these new features in inorganic fluorine chemistry and its industrial applications. The authors are outstanding experts in their fields, and the contents of the book should prove to be of valuable assistance to all chemists, graduates, students and researchers in the field of fluorine chemistry.

Book Description
Advanced Fluoride-Based Materials for Energy Conversion provides thorough and applied information on new fluorinated materials for chemical energy devices, exploring the electrochemical properties and behavior of fluorinated materials in lithium ion and sodium ion batteries, fluoropolymers in fuel cells, and fluorinated carbon in capacitors, while also exploring synthesis applications, and both safety and stability issues. As electronic devices, from cell phones to hybrid and electric vehicles, are increasingly common and prevalent in modern lives and require dependable, stable chemical energy devices with high-level functions are becoming increasingly important. As research and development in this area progresses rapidly, fluorine compounds play a critical role in this rapid progression. Fluorine, with its small size and the highest electronegativity, yields stable compounds under various conditions for utilization as electrodes, electrolytes, and membranes in energy devices. The book is an ideal reference for the chemist, researcher, technician, or academic, presenting valuable, current insights into the synthesis of fluorine compounds and fluorination reactions using fluorinating agents. - Provides thorough and applied information on new fluorinated materials for chemical energy devices - Describes the emerging role of stable energy devices with high-level functions and the research surrounding the technology - Ideal for the chemist, research, technician, or academic seeking current insights into the synthesis of fluorine compounds and fluorination reactions using fluorinating agents
