Among many types of energy storage devices, supercapacitors have played an important role in various fields due to the advantage of high power density and long cycle life. By the way, conventional EDLC type supercapacitors have some limitations for wide usage because of low energy density. Here, to overcome this problem, Graphene/Nickel Oixde hybrid composite has been considered as a promising electrode material for realizing ultra-high capacity pseudocapacitor. since the carbon nanotube branches are growth directly on the surface of the carbon nanotube or graphene, excellent interface characteristics can be realized and 3D carbon structure can be obtained in a short time due to microwave synthesizing method. Therefore, it has a lot of advantages in term of practical use. In this work, we present the synthesis method, unique structure and physical properties of Nickel hybrid composites, as well as their electrochemical and related applications, and outlook for future research. |
