Hydrogels

The demand for advanced energy devices such as high-performance batteries, supercapacitors, fuel cells, electrolyzers, and flexible/wearable devices is increasing rapidly. To meet such demand, high-performance and stable materials that could be used as active materials in these devices are much needed. This book focuses on the use of hydrogels in such emerging applications.
The main objective of this book is to provide current, state-of-the-art development in hydrogel-based materials, their applications in energy, and their future challenges. This book covers the entire spectrum of hydrogels for their applications in a range of energy devices in terms of materials, various synthetic approaches, architectural aspects, design and technology of energy devices, and challenges. This book covers the fundamentals of hydrogels, various composites of hydrogels, design concepts, different technologies, and applications in the diverse energy area. All chapters are written by experts in these areas around the world, making this a suitable textbook for students and providing new guidelines to researchers and industries working in these areas.
This book includes topics such as various approaches to synthesizing hydrogels, their characterizations, and emerging applications in the energy area. Fundamentals of energy devices, working principles, and their challenges are also covered. This book will provide new directions to scientists, researchers, and students to better understand hydrogel-based materials and their emerging applications in energy.
