“…Recently, research on carbon materials and graphene as anode materials for lithiumion batteries has been conducted [2][3][4]. There are several types of carbon allotropes [5,6], including graphene, graphite, diamond, carbon nanowalls (CNW), carbon nanotubes (CNT), and fullerenes. Graphene has a flat 2D structure in which carbon atoms form sp 2 bonds in a hexagonal shape, while graphite is a structure in which graphene forms multiple layers by π-π bonds [7,8].…”

Carbon nanowall (CNW) and carbon nanotube (CNT) were prepared as anode materials of lithium-ion batteries. To fabricate a lithium-ion battery, copper (Cu) foil was cleaned using an ultrasonic cleaner in a solvent such as trichloroethylene (TCE) and used as a substrate. CNW and CNT were synthesized on Cu foil using plasma-enhanced chemical vapor deposition (PECVD) and water dispersion, respectively. CNW and CNT were used as anode materials for the lithium-ion battery, while lithium hexafluorophosphate (LiPF6) was used as an electrolyte to fabricate another lithium-ion battery. For the structural analysis of CNW and CNT, field emission scanning electron microscope (FE-SEM) and Raman spectroscopy analysis were performed. The Raman analysis showed that the carbon nanotube in composite material can compensate for the defects of the carbon nanowall. Cyclic voltammetry (CV) was employed for the electrochemical properties of lithium-ion batteries, fabricated by CNW and CNT, respectively. The specific capacity of CNW and CNT were calculated as 62.4 mAh/g and 49.54 mAh/g. The composite material with CNW and CNT having a specific capacity measured at 64.94 mAh/g, delivered the optimal performance.

"Graphene oxide (GO) from sugar cane bagasse (SCB/F) was treated with EDTA to produce modified GO (EGO) by a hydrothermal preparation reaction. Raman spectra showed an intensity ratio of ID/IG for SCB/F and EGO8:1 (EDTA:GO 8:1) of 0.598 and 0.391, respectively. FTIR spectra confirmed the introduction of nitrogen-containing groups into the SCB/F backbone. SEM analysis demonstrated the porosity character for the sample. The TGA/DTA results implied the EGO8:1 sample was less thermally stable than SCB/F. The Ni2+ adsorption study revealed a steadily increasing adsorption of Ni2+ until 45 min, with no noticeable increase in adsorption after that. The results of kinetic modeling, adsorption isotherms, and thermodynamic parameters showed that the pseudo-second-order models gave a better fit to the adsorption data of the SCB/F and EGO samples. Also, the adsorption data fitted the Langmuir model best, and the negative values of G indicated that the sorption process was spontaneous."
