“…Supercapacitors are considered as one of the most useful devices for storing energy and hence they have grabbed a lot of attention as high performance electrochemical energy source [3]. They deliver high capacitance, rapid charge-discharge cycles, excellent cycle life, and are cost-effective [4][5][6]. Supercapacitors are mainly classified into three types: electric double layer capacitor (EDLC), pseudocapacitor and hybrid [7].…”

Supercapacitors are the energy storage devices that have gained increased attention due to high charge storage capacity, fast charge-discharge rate, high specific power and excellent cycle stability. Recently, research on supercapacitors is focused on the development of new electrode materials prepared by surface engineering to obtain superior electrochemical performance. Carbonaceous materials (CM) such as graphene, graphene oxide (GO), reduced graphene oxide (rGO) and carbon nanotubes (CNTs) etc. and conducting polymer (CP) based composite materials have gained increased attention for their use in supercapacitors. The nanocomposites obtained by merely mixing these two components pose some serious drawbacks such as low conductivity or poor film forming ability. The conjugation of CPs to CMs through covalent bonds is able to address these drawbacks. This review mainly provide collective information about various synthetic strategies to obtain CP grafted CMs for supercapacitor application. Herein, we provide information on different CP-CM conjugation reactions for obtaining the composites and their effects on electrochemical performances. The analysis revealed the importance of CP-CM grafting is important for tuning the electrochemical properties of the materials.

This work reports the preparation and testing of a composite material composed of α-Manganese dioxide (α-MnO2) coated with polyaniline (PANI) and reduced graphene oxide (rGO) for supercapacitor application. The structure and morphology of the materials were characterized by using X-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), thermogravimetric analysis (TGA) and Raman spectroscopy. The electrochemical performances of the materials were investigated by using cyclic voltammetry (CV), Galvanostatic charge–discharge (GCD), cyclic stability and electrochemical impedance spectroscopy (EIS). The α-MnO2-coated PANI/rGO nanocomposite exhibited a specific capacitance of 261 F g−1 at the scan rate of 5 mV s−1 with 75% capacitance retention after 2000 cycles at 5 A g−1. It showed a specific energy of 11 W h kg−1 and specific power of 1250 W kg−1.
