Supercapacitors and Their Applications Owing to their high power density, long life, and environmental compatibility, super- capacitors are emerging as one of the promising storage technologies, but with chal- lenges around energy and power requirements for specific applications. This book focuses on supercapacitors including details on classification, charge storage mecha- nisms, related kinetics, and thermodynamics. Materials used as electrodes, electro- lytes, and separators, procedures followed, characterization methods, and modeling are covered, along with emphasis on related applications. Features: • Provides an in-depth look at supercapacitors, including their working con- cepts and design • Reviews detailed explanation of various characterization and modeling techniques • Gives special focus to the application of supercapacitors in major areas of environmental as well as social importance • Covers cyclic voltammetry, charging–discharging curves, and electrochem- ical impedance spectroscopy as characterization techniques • Includes a detailed chapter on historical perspectives on the evolution of supercapacitors This book is aimed at researchers and graduate students in materials science and engineering, nanotechnology, chemistry in batteries, and physics.
