Owing to their high-power density, long life, and environmental compatibility, supercapacitors are emerging as one of the promising storage technologies, but with challenges around energy and power requirements for specific applications. This book focusses on supercapacitors including details on classification, charge storage mechanisms, related kinetics, and thermodynamics. Materials used as electrodes, electrolytes, and separators, procedures followed, characterization methods, and modeling are covered, along with emphasis on related applications.

The book focuses mainly on two major aspects of supercapacitors: fundamentals and their specific applications. In spite of the various advanced scientific concepts developed for the design of highly efficient supercapacitor systems, there are still lacunae to filled in the comprehensive literature on the topic, mainly in the perspective of broad application areas. Hence the book tries to capture all the available knowledge starting from the historical background to latest applications, taking into account the commercial as well as academic interests of the readers. Significant basic concepts of supercapacitors such as their classification; charge storage mechanisms; kinetics and thermodynamics of the processes; materials used as electrode, electrolyte, and separators; and procedures followed are covered in the initial part. This will especially help the academicians and researchers in rationalizing the materials and designs that can be taken up further. Potential material characterization methods and modeling are also covered in the book in a simple way which makes reading interesting for beginners. The latter part of the book discusses the future directions and prospects of supercapacitor technology, starting from the manufacture of industrial supercapacitors extending to specific applications like electric vehicles, solar cells, wind turbines, AC line filtering, and load leveling. Advanced supercapacitor applications in the biomedical, military, and aerospace sectors are also provided in this section.

There are a wide variety of capacitors depending on the practical application. The main categories are variable capacitors and non-variable capacitors. The capacitance value of variable capacitors can be changed mechanically or electronically, as the name suggests, whereas a non-variable capacitor gives fixed capacitance. Capacitors are mainly classified into three categories, namely electrostatic capacitors, electrolytic capacitors, and electrochemical capacitors.

EDLC/goldcaps/ultracapacitors/supercapacitors have been considered to be a well-tried alternative energy storage device for the last few decades. Owing to their power profile and ultra-long lifespan, the demand for novel designs and configurations in electric double-layer capacitors (EDLCs) is rapidly increasing and is especially so as there are diverse application areas being developed, constantly expanding the market. Their function also varies depending upon the specific application, wherein it would augment the battery technology or replace it.

In the present era, we can’t even imagine a world without modern portable electronic gadgets like smartphones, wireless devices, smartwatches, laptops, cameras, etc. Nowadays, the significance of flexible, wearable, and portable electronic devices is increasing in various sectors like smart electronics, consumer goods, sports, mobility, security and defence, medical and biomedical, green environment, clean energy, etc.. Smart devices launched recently include not just computers or smartphones but every component of smart home technology. Smart electronic devices generally require huge energy and need to be powered by efficient energy storage devices. Conventional batteries help devices run for a long time on a single charge. The expeditious growth of smart and portable electronics demands flexible, lightweight, small, and wearable power sources. Capacitors are now becoming a key component of basic portable electronics as well as the most modern smart/hybrid electric vehicles by providing rapid delivery of energy despite their poor storage capacity. Researchers are still working hard towards technologies to increase the storage ability of capacitors, strictly maintaining the green energy protocol. Supercapacitors (SCs) are found to be a better choice for addressing the energy issues of the portable electronic device industry.
