Carbon Nanotube-Based Supercapacitors
Due to the need for increased power performance, supercapacitors are emerging as an alternative to conventional electric energy storage devices. Because of their unique properties, carbon nanotubes are a promising material for next generation supercapacitors. Specifically, the use of nanotubes to construct supercapacitor electrodes can increases the power density and performance of supercapacit...
متن کاملCarbon Nanotube Supercapacitors
Supercapacitors (aka, electrochemical capacitors or ultracapacitors) are electrochemical energy storage devices that combine the high energy-storage-capability of conventional batteries with the high power-delivery-capability of conventional capacitors (Burke, 2000; Conway, 1999). Able to achieve higher power and longer cycle life than batteries, supercapacitors have been developed to provide p...
متن کاملMolecular dynamics simulation of polyethylene on single wall carbon nanotube.
Molecular dynamics simulations are carried out on the isothermal crystallization process of single polyethylene chains with different chain lengths on the single wall carbon nanotube. This process is summarized as two steps, i.e., adsorption and orientation, and the bond-orientational order parameter is used to show the details of this process. The results show that the attractive van der Waals...
متن کاملPseudocapacitive Effects of N-Doped Carbon Nanotube Electrodes in Supercapacitors
Nitrogenand micropore-containing carbon nanotubes (NMCNTs) were prepared by carbonization of nitrogen-enriched, polymer-coated carbon nanotubes (CNTs), and the electrochemical performances of the NMCNTs with different heteroatom contents were investigated. NMCNTs-700 containing 9.1 wt% nitrogen atoms had a capacitance of 190.8 F/g, which was much higher than that of pristine CNTs (48.4 F/g), de...
متن کاملCarbon nanotube structures: molecular dynamics simulation at realistic limit
Single walled carbon nanotubes as all-carbon molecules of tubular form exemplify modern nanometre scale material structures, where the number of atoms range from less than a million up to few millions. Such system are quite ideal for computational studies like Molecular Dynamics simulations because the studies can be done at the realistic limit, rendering them in a way predictive. This point of...
