6 FAQs about [Can rgo store sodium ]
What is the storage capacity of RGO cathode?
The RGO cathode shows a high sodium storage capacity of 240 mAh g −1 at a current density of 30 mA g −1 over 1000 cycles, which indicates the excellent stability of this material. The morphological and physical characteristics of the reduced graphene oxide prepared by modified Hummer’s method 41 are shown in Fig. 1.
Does rGO have nanocavities?
The RGO sheetpossesses nanocavities with single layer graphene ∼0.6 nm in thickness (G–L). It is found that the defects and single layer graphene coexist in the RGO host, with a thickness of ∼0.8 nm for the small RGO sheet (E–F).
Does rGO have a functionalized surface?
The relative contents of C and O were detected and plotted against distance (Fig. 1e). The average atomic ratios of C and O were measured to be 91.2 and 8.8 at.%, respectively. The contents show that the RGO has an extensively functionalized surface and could act more effectively for charge storage.
Can reduced graphene oxide be used as a cathode material for sodium-ion batteries?
Scientific Reports 7, Article number: 40910 (2017) Cite this article We report the feasibility of using reduced graphene oxide (RGO) as a cost-effective and high performance cathode material for sodium-ion batteries (SIBs). Graphene oxide is synthesized by a modified Hummers’ method and reduced using a solid-state microwave irradiation method.
What is the C K-edge NEXAFS spectrum of RGO?
Figure 3b shows the C K-edge NEXAFS spectrum of RGO, where the electronic transition occurs from the core level to unoccupied states into π* C = C symmetry around the K and M points of graphene oxide layers and the corresponding peak occurs at 285.3 eV.
Does RGO show good cycling performance and rate capability?
It can be expected that RGO could show good cycling performance and rate capability due to its adsorption mechanism. The outstanding cycling performance of RGO is shown in Fig. 4 a. The electrochemical performance was tested at 0.2 C (40 mAh g −1) and 1 C (200 mAh g −1 ), respectively.
