This book covers the rapidly growing area of advanced materials for hybrid supercapacitors, which has attracted the attention of researchers all over the world. Beginning with a brief introduction to the physical and technical fundamentals of hybrid supercapacitors and their charge storage mechanisms, the subsequent chapters — authored by active researchers in the field — focus, in particular the synthesis, characterization, and performance of different sulfide, selenide, and metal–organic-framework-based materials and their composites. Additionally, the book features special chapters dealing with polymer electrolyte-based hybrid supercapacitors for lightweight flexible devices, and the unique challenges present in fabricating, patenting, and commercializing flexible devices for uptake in the broader market. This book is ideal for materials engineers and scientists working in supercapacitor research and technology.
