The Zinc/Bromine Flow Battery

This book presents a detailed technical overview of short- and long-term materials and design challenges to zinc/bromine flow battery advancement, the need for energy storage in the electrical grid and how these may be met with the Zn/Br system. Practical interdisciplinary pathways forward are identified via cross-comparison and comprehensive review of significant findings from more than 300 published works, with clear in-depth explanations spanning initial RFB development to state-of-the-art research in related systems. Promising strategies described include the use of modern electrochemical techniques to study and optimize physical processes occurring within the system during operation, improving zinc electroplating quality during the charge phase through the strategic use of organic additives, as well as identifying suitable catalysts to optimize the bromine/bromide redox couple. The primary focus is on research and development of novel materials in the areas of electrolyte formulation and multifunctional “smart” electrode surfaces to achieve a higher degree of control over processes at the electrode–electrolyte interface. The strategies suggested in this book are also highly adaptable for use in other similar flow battery systems, while the unique cross-comparative approach makes it a useful reference and source of new ideas for both new and established researchers in the field of energy storage and battery technology.
