Abstract: Electrical double layer model describes the structure of the charge layer between the electrical pole and electrolyte solution interface, it constitutes one of the fundamental theories for the modern electrochemistry. Electrical double layer indicates the equilibrium behavior of charge and electrode kinetics in an electrochemical process. Many today's technologies are based on this theory, including electrochemical analysis, double layer capacitor and so on. This article reviews the evolution of electrical double layer concept and related mathematical models, We hope the review would benefit the future development of modern electrochemistry.

Key words: electrical double layer, electrochemistry, mathematical model, kinetics of electrode process
