Abstract: Electrochemical capacitors (supercapacitors) have been developed as a new type of energy storage device with high energy and power densities, which have the advantages of both fast charging-discharging as traditional capacitors and high energy density as batteries. Notable improvements in their electrochemical performance have been achieved in recent years owing to the recent advances in understanding of charge storage mechanisms and the development of advanced nanostructured materials. Recently, modeling and simulation of these supercapacitors has been applied as a useful approach to better understand the working mechanisms of the supercapacitors by describing the concentrations and electric fields inside the capacitors. Particularly, the continuous models for supercapacitors, which can provide insights into the mass transport and interfacial phenomena in supercapacitors under different operating conditions, have been drawing more and more attention. And there is no review article addresses this topic so far. This paper will try to summarize the basic theories of supercapacitors and the latest progresses in the continuous models for supercapacitors. The focus is the recent advances in the application of continuous models to optimize device parameters under different conditions. Meanwhile, the prospects and challenges associated with the continuous models in the future are also discussed. We believe that modelling of supercapacitors could help design the next-generation supercapacitors for versatile electronic devices.

Key words: electrochemical capacitors, charge storage mechanisms, nanostructured materials, continuous models
