Electrochemical Supercapacitors: History, Types, Designing Processes, Operation Mechanisms, and Advantages and Disadvantages

Abstract

The perception of electrochemical supercapacitors (ESs) depended on the electric double-layer (EDL) existing at the interface between a conductor and its contacting electrolyte solution. The electric double-layer theory was the first proposed by Hermann von Helmholtz in 1853 and further developed by Gouy, Chapman, Grahame, and Stern. This chapter provides in depth information on the histroy of supercapacitors, their types, designing processes, operation mechanisms and advantages and disadvatnages.
