Excellent Cyclic Retention and Supercapacitive Performance of Electrochemically Active Nanocomposite Electrode

Abstract

In this work, electrochemically active polydiphenylamine-silica reinforced graphene nanocomposite was prepared via an interfacial chemical oxidative polymerization method for energy storage application. The morphological views of synthesized nanocomposite were captured through scanning electron microscope (SEM). The supercapacitance behaviour of fabricated modified electrode was investigated by electrochemical analyses such as galvanostatic charge–discharge (GCD) and bode plot experiments. These results found that the chemically modified nanocomposite provides a high conductivity and also an afforded specific capacitance of ∼433 F/g with good cycling retention of 91% upto 500 cycles. Furthermore, the attained data will help in the profound study and further developments in energy storage device applications.
