The idea of this book is to provide readers who are researchers, undergraduates, and postgraduate students with a comprehensive understanding of supercapacitors. The fundamentals of electrochemistry will help the reader understand the importance of various components of supercapacitors and their selection in attaining optimal performance. Capacitors in other forms are also described for contrast and to relate the differences in the materials that are used to make
