High performance supercapacitor based on thick buckypaper/polyaniline composite electrodes

Abstract

Large-size composite carbon nanotubes/polyaniline as supercapacitor electrode material has been investigated for optimization of the areal specific capacitance. Polyaniline, as conductive polymer, is synthesized on the structure of carbon nanotubes by an in situ method. Thicker the composite electrode and higher polyaniline loading increase the gravimetric and volumetric specific capacitance. It is noticeable that this report's areal specific capacitance can reach approximately 6.5 F cm −2 .

A single carbon nanotube-entangled high-performance buckypaper with tunable fracture mode

“…[8][9][10][11][12][13] Due to their outstanding mechanical, 14,15 thermal, 16 and electrical properties 17,18 and chemical stability, 19,20 BPs have broad potential applications in electrode materials, filters, sensors, actuators and multifunctional devices. [21][22][23] Ever since the BP was first fabricated by Liu et al in 1998, 24 researchers have made great efforts to explore its mechanical properties using experimental and theoretical calculations. [25][26][27][28][29][30][31] Computer simulations such as ab initio molecular dynamics and classic molecular dynamics have been extensively used to study the mechanical properties of carbon based nanostructured material systems and several important achievements have been obtained.…”

Thin carbon–polypyrrole composite materials for supercapacitor electrodes by novel bipolar electrochemical setup

“…These materials have common applications in supercapacitors as well as other electrochemical fields such as electrodes for fuel cells, batteries, and electrolyzers. [27][28][29][30][31][32][33] PPy belongs to a special class of polymers known as conductive polymers. A conjugated network in the polymer backbone allows charge to travel along the chain.…”

Highly porous nanocomposite of NiMoS4 nanosheets and reduced graphene oxide for energy storage application

“…Supercapacitors (SCs), also known as electrochemical capacitors, have been widely studied for alternative energy storage devices because they possess high power capabilities, high charge/discharge rates, and very long cycle-life [1][2][3][4][5][6]. However, SCs still have a low energy density and are not yet practical applications.…”
