Wearable Textile Energy Storage and Conversion Systems brings together the latest research into wearable energy systems, functional materials, power generation, thermal management, integrated energy systems and storage, and novel smart devices in this rapidly developing and highly interdisciplinary area. The book begins by introducing development, classification, and configuration techniques for textile wearable energy storage and conversion systems. This is followed by detailed chapters that focus on individual types, covering in turn lithium-based batteries, sodium-Ion batteries, zinc-based batteries, other metal-based batteries, nanogenerators, supercapacitors, fuel cells, and solar cells. The book's final chapters discuss emerging applications, integration and large-scale production, key challenges, and future prospects. This is a valuable resource to all those with an interest in flexible energy storage and conversion techniques, flexible and functional electronics, materials synthesis and fabrication, smart textiles, and wearable technologies, including researchers, engineers, scientists, graduate students, and R&D personnel.
