Theories and models of supercapacitors with
Devices for storing and converting electrochemical energy from on form to another include supercapacitors, batteries and fuel cells.
Electrochemical capacitors, which are commercially called supercapacitors or ultracapacitors, are a family of energy storage devices with remarkably high specific power compared with other electrochemical storage devices.
Electrochemical supercapacitors (ECSCs) fall in between EDLCs and batteries. ECSCs use metal oxide or conducting polymer electrodes with a high amount of electrochemical pseudocapacitance additional to the double-layer capacitance.
The electrochemical supercapacitors are classified into three categories based on the charge storage mechanism: (1) electrochemical double-layer capacitors (EDLCs), (2) pseudocapacitors, and (3) hybrid capacitors. EDLCs consist of two electrodes and an electrolyte.
Hybrid electrochemical supercapacitors (HEC) has a cathode like that of an EDLC and a carbon anode that is doped with metal oxides like lithium titanate. The asymmetry in the electrode properties give them increased energy density. The type of electrolyte determines the voltage level that can be achieved with these types of supercapacitors.
