                                                      Supercapacitors

 

            Supercapacitors have a wide range of applications, from energy harvesting, hybrid vehicles to smartphones. Depending upon the nature of the material used and mechanism of operation, supercapacitors are classified into two; electrical double-layer capacitors (EDLC) and pseudocapacitors. The mechanism of charge storage in EDLC is through electrostatic charge which gets accumulated at the electrode-electrolyte interface. In contrast, the pseudocapacitor depends on the quick and reversible faradaic process that takes place due to electro-active species. We study the pseudo and hybrid supercapacitors at NSRL.
