“…The high specific capacitance of CNTs could also be obtained with the incorporation of heteroatoms such as N [61,[78][79][80][81][82][83][84][85][86][87], B [86][87][88][89], P [86,90], and F [91]. The type of defect created by the heteroatom influences the kind of conduction generated ranging from n-type transport (N substitution doping) to p-type conduction (B substitution of boron in lattice) [92].…”

“…The type of defect created by the heteroatom influences the kind of conduction generated ranging from n-type transport (N substitution doping) to p-type conduction (B substitution of boron in lattice) [92]. The existence of heteroatoms significantly enhances the specific capacitance values of carbon materials by the pseudocapacitance effect [83,88]. Gueon and co-workers found that nitrogen-doped carbon nanotubes have a specific capacitance three times higher compared to undoped carbon nanomaterial [79].…”

“…Thermal oxidation [88] or acid treatment [81] of doped CNTs improves the specific surface area and, as a consequence, the capacitance due to the tube end opening process. Coaxial supercapacitors based on hollow carbon nanotubes synthesized by chemical vapor deposition (CVD) exhibit high rate capacitance, long cycle life, and good flexibility [93].…”

“…The effect of B-doping on the capacitance can be explained by modification of the space charge layer in carbon. The presence of boron leads to the enhancement of the space-charge layer capacitance through increasing the number of holes as a charge carrier or the DOS change at the Fermi level [88].…”

This review is focused on the theoretical and practical aspects of electrochemical c a p a c i t o r sb a s e do nc a r b o nn a n o t u b e s .I np articular, recent improvements in the capacitance properties of the systems are discussed. In the first part, the charge storage mechanisms of the electrochemical capacitors are briefly described. The next part of the review is devoted to the capacitance properties of pristine single-and multi-walled carbon nanotubes. The major portion of the review is focused on the capacitance properties of modified carbon nanotubes. The electrochemical properties of nanotubes with boron, nitrogen, and other atoms incorporated into the carbon network structure as well as nanotubes modified with different functional groups are discussed. Special attention is paid to the composites of carbon nanotubes and conducting polymers, transition metal oxides, carbon nanostructures, and carbon gels. In all cases, the influences of different parameters such as porosity, structure of the electroactive layer, conductivity of the layer, nature of the heteroatoms, solvent and supporting electrolyte on the capacitance performance of hybrid materials are discussed. Finally, the capacitance properties of different systems containing carbon nanotubes are compared and summarized.

“…Recently Leitner et al reported a nitrogen-containing carbon material with high pseudo-capacitance even in the absence of substantial surface area [27]. Faradaic redox reactions exhibited by carbon materials containing nitrogen are extensively studied for the capacitors applications by many researchers over the globe [28][29][30][31].…”

Templated Nanocarbons for Energy Storage

2012

View full text Add to dashboard Cite

The template carbonization method is a powerful tool for producing carbon materials with precisely controlled structures at the nanometer level. The resulting templated nanocarbons exhibit extraordinarily unique (often ordered) structures that could never be produced by any of the conventional methods for carbon production. This review summarizes recent publications about templated nanocarbons and their composites used for energy storage applications, including hydrogen storage, electrochemical capacitors, and lithium-ion batteries. The main objective of this review is to clarify the true significance of the templated nanocarbons for each application. For this purpose, the performance characteristics of almost all templated nanocarbons reported thus far are listed and compared with those of conventional materials, so that the advantages/disadvantages of the templated nanocarbons are elucidated. From the practical point of view, the high production cost and poor mass-producibility of the templated nanocarbons make them rather difficult to utilize; however, the study of their unique, specific, and ordered structures enables a deeper insight into energy storage mechanisms and the guidelines for developing energy storage materials. Thus, another important purpose of this work is to establish such general guidelines and to propose future strategies for the production of carbon materials with improved performance for energy storage applications.
