“…It can be observed that the intensity of this band decreases in the case of the as prepared RGOs when compared to that of GO. The ID/IG ratio of Fe-RGO is 1.19 and Sn-RGO is 1.14, which are higher than that of graphite (ID/IG = 0.34), indicating a highly disordered nature of the RGO sheets and the associated unrepaired edge defects [4]. These results are in coherence with the XRD and FESEM data.…”

“…Such sloping behaviour can be accredited to the reversible interaction of sodium at vacancies and Stone-Wales (SW) defects [4]. The Fe-RGO and Sn-RGO showed a specific discharge capacity of 202 and 272 mA h g -1 in the second cycle respectively.…”

“…One particular disadvantage of sodium is its relatively larger ionic radius than lithium (1.02 Å of Na + vs. 0.76 Å of Li + ), thus requiring larger channels for transport and interstitial sites for sodium ions [4]. Recent research has been focusing on identifying and developing suitable electrode materials for the sodium-ion energy storage technology.…”

AbstractThe performance of few-layered metal-reduced graphene oxide (RGO) as a negative electrode material in sodium-ion battery was investigated. Experimental and simulation results indicated that the as-prepared RGO with a large interlayer spacing and disordered structure enabled significant sodium-ion storage, leading to a high discharge capacity. The strong surface driven interactions between sodium ions and oxygen-containing groups and/or defect sites led to a high rate performance and cycling stability. The RGO anode delivered a discharge capacity of 272 mA h g -1 at a current density of 50 mA g -1 , a good cycling stability over 300 cycles and a superior rate capability. The present work provides new insights into optimizing RGOs for high-performance and low-cost sodium-ion batteries.

“…Because Na + ions cannot be easily intercalated into the layers of graphite due to larger radius of Na + , resulting in a low capacity of 31 mAh g −1 , conventional graphite might not be suitable for SIBs 3. However, various amorphous carbon materials including hollow nanostructured carbons,4 carbon nanospheres,5 carbon nanofibres,6 carbon nanosheets,7 porous carbons,8 hard carbon,9 graphene,10 and heteroatom‐doped carbon materials11 are being investigated as anode for SIBs in full swing, benefiting from disordered nanodomains with randomly oriented graphene layers and voids between these domains, which can provide rich active sites for storing Na + 9, 12. Unfortunately, lots of amorphous carbon‐based anode materials are accompanied with low initial columbic efficiency and poor specific capacity at high current density.…”

Large‐Area Carbon Nanosheets Doped with Phosphorus: A High‐Performance Anode Material for Sodium‐Ion Batteries

Large‐area phosphorus‐doped carbon nanosheets (P‐CNSs) are first obtained from carbon dots (CDs) through self‐assembly driving from thermal treatment with Na catalysis. This is the first time to realize the conversion from 0D CDs to 2D nanosheets doped with phosphorus. The sodium storage behavior of phosphorus‐doped carbon material is also investigated for the first time. As anode material for sodium‐ion batteries (SIBs), P‐CNSs exhibit superb performances for electrochemical storage of sodium. When cycled at 0.1 A g−1, the P‐CNSs electrode delivers a high reversible capacity of 328 mAh g−1, even at a high current density of 20 A g−1, a considerable capacity of 108 mAh g−1 can still be maintained. Besides, this material also shows excellent cycling stability, at a current density of 5 A g−1, the reversible capacity can still reach 149 mAh g−1 after 5000 cycles. This work will provide significant value for the development of both carbon materials and SIBs anode materials.

For anode materials in SIBs, various carbon materials have been reported because of their relatively high capacity and cyclability [13][14][15] . Among them, graphite is an intriguing material with different lithium and sodium storage properties (372 mA h g À 1 in LIBs, but less than 35 mA h g À 1 in SIBs).…”

Na+ intercalation pseudocapacitance in graphene-coupled titanium oxide enabling ultra-fast sodium storage and long-term cycling

Sodium-ion batteries are emerging as a highly promising technology for large-scale energy storage applications. However, it remains a significant challenge to develop an anode with superior long-term cycling stability and high-rate capability. Here we demonstrate that the Na þ intercalation pseudocapacitance in TiO 2 /graphene nanocomposites enables high-rate capability and long cycle life in a sodium-ion battery. This hybrid electrode exhibits a specific capacity of above 90 mA h g -1 at 12,000 mA g -1 (B36 C). The capacity is highly reversible for more than 4,000 cycles, the longest demonstrated cyclability to date. First-principle calculations demonstrate that the intimate integration of graphene with TiO 2 reduces the diffusion energy barrier, thus enhancing the Na þ intercalation pseudocapacitive process. The Na-ion intercalation pseudocapacitance enabled by tailor-deigned nanostructures represents a promising strategy for developing electrode materials with high power density and long cycle life.
