Potentiodynamic Deposited Electrodes For SUPERCAPACITIVE MEASURMENTS

In the 21st century, the world is growing towards the need of energy and power required for different applications. Supercapacitor/electrochemical supercapacitor (ES) or Ultra capacitor have attracted significant attention as an energy/power density resource. Supercapacitors have been received a lot of applications in the field of power/energy storage of hybrid electrical vehicles, mobiles and digital communications, military, missiles etc. To improve the performance of supercapacitor electrode, preferably it requires conducting current collectors and coated material which is chosen with multi oxidation states, good electrical conductivity, mixed capacitive behaviour, semi crystalline (amorphous as well as crystalline), porous and hydrophilic nature, ideal polarizability, low ESR etc. The aim of work is to carry out the systematic study essential to improve the performance of cobalt oxide electrode prepared by Potentiodynamic electrodeposition.
