Supercapacitors: Materials, Design, and Commercialization

Supercapacitors: Materials, Design, and Commercialization provides a comprehensive overview of the latest research trends and opportunities in supercapacitors, particularly in terms of novel materials and electrolytes. The book addresses the transformation in supercapacitive technology from double layer capacitance to battery-type capacitance, providing a clear understanding of the conceptual differences between various charge storage processes for supercapacitors, charge storage based on materials and electrolytes, and calculation for capacitance for these charge processes. Detailed chapters discuss recent developments in materials, such as carbons, chalcogenides, MXene and phosphorene, various polymer nanocomposites, and polyoxometalates for supercapacitors.

This is followed by in-depth coverage of electrolytes, including the evolution of electrolytes from aqueous to water-in-salt electrolytes and their role in improving the energy density of supercapacitors. The final part of the book examines the role of artificial intelligence in the design of supercapacitors, and latest developments in translating novel supercapacitor technologies from laboratory-scale research to a commercialization.

• Brings together the latest developments in supercapacitor materials and electrolytes
• Discusses cutting-edge charge storage concepts and methods for supercapacitors
• Addresses the role of machine learning and the scale-up from laboratory to commercialization

Dr. Syam G. Krishnan is a Postdoctoral Research Fellow at Queensland University of Technology (QUT), Australia. With a research background in nanomaterials for supercapacitors, Dr. Krishnan’s research focuses on synthesis, tailored morphology, and conductivity of metal oxides and their composites, ternary metal cobaltites, polymer nanocomposites, and activated carbon for supercapacitors. At QUT, he is working on recycling of battery materials for supercapacitors, metal-ion batteries, and wearable electronics.
