At any electrode immersed in an electrolyte solution, a specific interfacial region is formed. This region is called the double layer. The electrical properties of such a layer are important, since they significantly affect the electrochemical measurements. In an electrical circuit used to measure the current that flows at a particular working electrode, the double layer can be viewed as a capa...

The double-layer capacitor (DLC) is a low voltage device exhibiting an extremely high capacitance value in comparison with other capacitor technologies of similar physical size. It’s also a promising device for certain power electronic application as energy storage. In this work, a three RC branch equivalent circuit is used to characterize its terminal behavior and the equivalent circuits resul...
