What are the two types of supercapacitors?
Supercapacitors are broadly categorized into two classes based on their charge storing mechanism, namely: (i) electrical double layer capacitor (EDLC), and (ii) pseudocapacitor (PC). The EDLC stores the charges in the form of an electric double layer (EDL) that has a charge separation distance of <1 nm.
Why do capacitors have a double-layer of charge?
Following the natural into the pores of the electrode of opposite charge. However, the electrodes are engineered to prevent the recombination of the ions. Thus, a double-layer of charge is produced at each electrode. These double-layers, coupled with an increase in surface area and a densities than conventional capacitors [1-3].
