The book Materials for Sustainable Energy Storage Devices at the Nanoscale anticipates covering all electrochemical energy storage devices such as supercapacitors, lithium-ion batteries (LIBs), and fuel cells,transformation and enhancement materials for solar cells, photocatalysis, etc. The focal objective ofthe book is to deliver stunning and current information to the materials application at nanoscale toresearchers and scientists in our contemporary time towardthe enhancement of energy conversion andstorage devices. However, the contents of the proposed book, Materials for Sustainable Energy Storageat the Nanoscale, will cover various fundamental principles and wide knowledge of different energyconversion and storage devices with respect to their advancement due to the emergence of nanoscalematerials for sustainable storage devices. This book is targeted to be award-winning as well as a referencebook for researchers and scientists working on different types of nanoscale materials-based energystorage and conversion devices. Features Fabian I. Ezema is a professor at the University of Nigeria, Nsukka. He earned a PhD in Physics and Astronomy from the University of Nigeria, Nsukka. His research focused on several areas of Materials Science, from synthesis and characterizations of particles and thin-film materials through chemical routes with emphasis on energy applications. For the last 15 years, he has been working on energy conversion and storage (cathodes, anodes, supercapacitors, solar cells, among others), including novel methods of synthesis, characterization and evaluation of the electrochemical and optical properties.
