CNT-Ni-Co-O based composite for Supercapacitor applications by Cyclic Voltametry analysis: A Short Quick Glimpse

Abstract

CNT based material are of vital importance in modern technology for their superior physical and chemical properties. In recent times, materials development for energy applications is focused for improvement of battery, capacitors, and electrodes for enhanced efficiency. High performance Supercapacitors with high energy densities are at the leading edge for renewable energy engineering device sector. CNT based Ni-Co-O material is of keen interest due to its possible applications as supercapacitors, electrocatalyst for metal/air battery and others. The hybrid material synthesis, morphological and electrochemical features are vital to evaluate the material performances for energy applications. Electrical studies are also important to evaluate the properties required for device applications. CNT is used as electrode material for electrochemical storage due to superior chemical stability, low mass density, low resistivity and large surface area. CNT replaces activated carbon material as supercapacitor due to improper balance between enhanced surface area and mesoporosity thus limiting electrolytic accessibility and capacitance. In the present article a brief review is stressed forward for the development of CNT-Ni-Co-O based hybrid material for supercapacitor high energy density applications.
