Modeling of electric double layer capacitor

Electric double layer capacitor (EDLC) is an energy storage device that fills the gap between battery and conventional capacitor. One way to understand EDLC’s charge storage mechanism is through its equivalent circuit analysis. Nonetheless, most of existing equivalent circuits proposed in the past r...
