A new way to simultaneously grow carbon nanotubes (CNTs) and ultrathin graphite on copper (Cu) foils has been investigated. This one-step growth process yields three-dimensional networks of CNTs on graphitic layers (3D CNTs/G) on Cu foils. Their synthesis conditions and growth mechanism are discussed in detail taking their structural properties into account. Individual CNTs and the 3D CNTs/G networks by means of an in-situ conductive atomic force microscope inside a scanning electron microscope are electrically characterized. Time-resolved photoluminescence demonstrated fast charge transfer and high carrier collection efficiency superior to two-dimensional ultrathin graphite only. Their facile and tunable growth and excellent electrical properties show that the 3D CNTs/G are strongly attractive for various applications such as solar cells, sensors, supercapacitors, photovoltaics, power generation, and optoelectronics.

“…The peak at 1560 cm ‒1 , named the G-band, corresponds to an E 2g vibration mode of sp 2 -bonded carbon atoms in graphene sheets. The peak at 1332 cm −1 , named the D-band, is associated with carbon atoms with structural defects and disorder in the graphitic structure [ 34 ]. The intensity ratio of D and G bands (I D /I G ) is calculated to be 1.49, also implying a low graphitization degree of carbon fibers.…”

Manganese monoxide (MnO) is a promising anode material in the lithium-ion battery for its high capacity, low operation potential, and environmental benignity. However, its application is impeded by poor rate capability and rapid capacity fading. In this work, a MnO/carbon hybrid material, in which small-sized MnO nanoparticles are tightly anchored on carbon fibers (denoted as MnO@CFs), was prepared by annealing the electrospun precursor fibers at 650 °C. When applied as the anode material of the Li-ion battery, the small size of MnO shortens the Li-ion diffusion path, and the carbon fibers not only greatly improve the conductivity but also efficiently buffer the MnO structure strain during the charge–discharge process, endowing the MnO@CFs electrode with a good rate capability (185 mAh g−1 at 5 A g−1) and cyclic stability (406 mAh g−1 after 500 cycles at 1.0 A g−1).

“…It can be clearly seen that the as-prepared B-CNTs show a better cyclability and stability compared to recent reports. 6,[39][40][41][42][43] The rate capability of Li ion batteries using the B-CNTs anode was also investigated. As shown in Fig.…”
