“…By the accurate determination of diffraction (002) however the three-dimensional ordering seems to be lack even after annealing at 2800°C. Considering the small diameter of MWNTs (ranging from 20 to 60 nm) in this study, the large curvature of the graphene sheet could might one of reason for the lack of three-dimensional stacking fidelity [17].…”

Systematic isothermal annealing has been carried out on catalytic chemical vapor deposition-derived highly disordered multi-walled carbon nanotubes in order to understand the structural evolution of carbon nanotubes kinetically. After specified isothermal time the crystallographic parameters strongly depend on annealing temperature, and can be divided into three stages. Rapid structural enhancement in the range from 1800 to 2200°C originates from the abrupt evolution of the residual catalytic compounds and is seen as partially aligned small fringes along the tube length. The lack of further structural ordering at temperatures above 2400°C and the low activation energy (ca. 90kJ/mol) are thought to be the result of the limited space available for further structural development considering the nano-sized multi-walled carbon nanotubes.2

“…Figure 2a shows the XRD patterns of SSC, S, and S/SSC composite. The synthesized SSC displays a strong diffraction peak at around 26°, which can be ascribed to the (002) reflection of carbon [21]. The S/SSC composite gives obvious peaks at 23.1°, 25.9°, 27.8°, 28.7°, 31.5°, 37.1°, 42.8°, 47.8°, and 51.3°, which are typical signals from orthorhombic sulfur (JCPDS #08-0247) [22].…”

A novel stacking sheet-like carbon (SSC) has been synthesized by carbonizing the corn stalks and composited with sulfur to prepare a cathode for lithium/sulfur batteries. Scanning electronic microscopy observations showed the formation of irregularly interlaced nanosheet-like structure consisting SSC with uniform sulfur coating on its surface. The SSC nanoflakes in the composite act as nanocurrent collectors, favoring the charge carrier ion transport and electrolyte diffusion. The interlaced SSC nanoflakes irregularly stack together and form a three-dimensional network, which is beneficial for both trapping soluble polysulfide intermediates and rendering the electrical conductivity of the composite electrode. A lithium cell employing this sulfur/stacking sheetlike carbon (S/SSC) composite cathode delivered an initial discharge capacity of 965 mAh g −1 at 0.2 C and retained a capacity of 743 mAh g −1 over 100 charge-discharge cycles.Even at 3.2 C rate, the lithium cell with the S/SSC composite cathode demonstrated an excellent rate capability, delivering a highly reversible discharge capacity of 418 mAh g −1.
