For super capacitors
, there can be different classification methods based on different contents.
First, according to different energy storage mechanisms, supercapacitors can be divided into two categories: electric double layer capacitors and Faraday quasi-capacitors. Among them, the electric double-layer capacitor mainly generates stored energy through the adsorption of pure electrostatic charges on the electrode surface. Faraday quasi-capacitors mainly generate Faraday quasi-capacitors through Faraday quasi-capacitance active electrode materials (such as transition metal oxides and high molecular polymers) on and near the surface of the reversible redox reaction to generate Faraday quasi-capacitors, thereby achieving energy storage and conversion.
Secondly, according to the type of electrolyte, it can be divided into two categories: water-based supercapacitors and organic supercapacitors.
In addition, according to whether the types of active materials are the same, they can be divided into symmetric supercapacitors and asymmetric supercapacitors.
Finally, according to the state and form of the electrolyte, supercapacitors can be divided into solid electrolyte supercapacitors and liquid electrolyte supercapacitors.
