“…Attempts have been made to try to solve these problems, for example, by cutting the nanotubes to short segments to improve the charge transfer capability of the electrode 353. With their improved properties mentioned earlier, VA–CNTs are attracting more and more attention as the new anode materials for Li‐ion batteries 354…”

“…It is then desirable to combine the high‐capacity‐capability of batteries with the high‐rate‐capability of supercapacitors to obtain a high‐energy and high‐power energy storage device. Along with the use of VA–CNTs and metal‐oxide hybrid electrodes in supercapacitors (Section 4.1.4), VA–CNTs have also been used in Li‐ion batteries either directly as electrode materials (Li + intercalation anode),69, 354 or as conductive substrates for the deposition of electroactive materials (e.g., conducting polymers326 and metal oxides290) to develop high‐capacity and high‐rate electrode materials 380. Therefore, a variety of materials (e.g., conjugated polymers,326 manganese oxide,290 and vanadium oxide)381 have been deposited onto VA–CNTs for cathode applications.…”

It is estimated that the world will need to double its energy supply by 2050. Nanotechnology has opened up new frontiers in materials science and engineering to meet this challenge by creating new materials, particularly carbon nanomaterials, for efficient energy conversion and storage. Comparing to conventional energy materials, carbon nanomaterials possess unique size-/surface-dependent (e.g., morphological, electrical, optical, and mechanical) properties useful for enhancing the energy-conversion and storage performances. During the past 25 years or so, therefore, considerable efforts have been made to utilize the unique properties of carbon nanomaterials, including fullerenes, carbon nanotubes, and graphene, as energy materials, and tremendous progress has been achieved in developing high-performance energy conversion (e.g., solar cells and fuel cells) and storage (e.g., supercapacitors and batteries) devices. This article reviews progress in the research and development of carbon nanomaterials during the past twenty years or so for advanced energy conversion and storage, along with some discussions on challenges and perspectives in this exciting field.

Vertically-aligned carbon nanotubes (VA-CNTs) have a large surface area, high electronic conductivity and electrochemical accessibility, and mechanical/ chemical/electrochemical stability. These unique properties make VA-CNTs promising electrode materials for energy conversion and storage devices, including fuel cells, lithium batteries, and supercapacitors. This chapter provides an overview on recent development of VA-CNT electrodes with and without heteroatom-doping for efficient energy conversion and storage by summarizing our work on the discovery of nitrogen-doped VA-CNTs as a highly active cathode for ORR in fuel cells, vertically aligned nitrogen doped coral-like carbon fiber arrays (VA-NCCFs) as a high-performance air cathode in Li-air batteries, as well as VA-CNTs and their 3D derivatives as porous electrodes in high-performance Li-ion batteries and supercapacitors.

“…Because of their prominent electrical, chemical, and mechanical properties, carbon nanotubes (CNTs) have been actively studied in relation to potential applications in a wide range of areas [1][2][3]. Double walled carbon nanotubes (DWNTs) consisting of two coaxial graphitic tubes have been of particular interest for applications including nanocomposites, electron emission sources and nanoelectronics [4].…”

We demonstrate the formation of precisely designed double-walled carbon nanotube (DWNT) structures via growth optimization of thermal chemical vapor deposition. Effects of various growth factors such as different catalyst film-and buffer layer-thicknesses, flow rates and growth time were investigated to produce desired DWNT structures. We used acetylene as the main feedstock and fabricated site selective DWNT vertical structures through a catalyst patterning process. The DWNT structures will be applicable to areas where mechanical stability with thin diameter is required, such as in nanotube-based composites, electron emission devices, heat release components in electric devices and nanoelectromechanical systems.
