According to the mechanism of storing electrical energy, supercapacitors can be divided into the following two types:
One is an "electric double layer capacitor" whose capacitance is mainly generated based on the electric double layer capacitance generated by the charge separation on the electrode P electrolyte, such as a carbon electrode capacitor; the other is called "Faraday quasi-capacitance", a noble metal and a noble metal oxide electrode, etc., whose capacitance is generated based on an underpotential deposition of an electroactive ion on the surface of a noble metal electrode, or an adsorption capacitance generated by a redox reaction occurring in a surface of a noble metal oxide electrode and a bulk phase, The generation of a class capacitor is different from that of an electric double layer capacitor, and with the occurrence of a charge transfer process, it usually has a larger specific capacitance.
According to the structure of the supercapacitor and the reaction on the electrode, it can be classified into the following two types. If the composition of the two electrodes is the same and the electrode reaction is the same, and the reaction direction is reversed, it is called a symmetrical type. Carbon electrode electric double layer capacitors, precious metal oxide capacitors are symmetrical type capacitors. If the composition of the two electrodes is different or the reaction is different, it is called an asymmetric type, and the capacitor which can be used as the electrode of the conductive polymer which can be doped with n-type and p-type is an asymmetric type capacitor, and its performance form is closer to the battery. Shows higher specific energy and specific power.
