“…No peaks of RGO are observed in the diffraction peaks of the Mn 2 Sb 2 O 7 /RGO composite, which may be attributed to the large amount of Mn 2 Sb 2 O 7 restraining the re-stacking of graphene. [28] As shown in Figure 1d, the removal of RGO (11.48 wt.%) is carried out in the temperature range of 300 to 500°C in the weight loss. Sb ion is coordinated with six oxygen ions forming the SbO 6 Raman spectrum of the samples (Figure 1c) was also studied to determine the presence of RGO.…”

For the advancement of lithium-ion batteries (LIBs), metal oxides with high theoretical specific capacities have been explored as anodes. Herein, we report a new metal oxide, Mn 2 Sb 2 O 7 -anchored reduced graphene oxide (Mn 2 Sb 2 O 7 /RGO), as an advanced anode for LIBs. The Mn 2 Sb 2 O 7 /RGO anode exhibits a higher capacity and better capacity retention compared to Mn 2 Sb 2 O 7 , because the close contact between Mn 2 Sb 2 O 7 and RGO facilitates charge transfer during cycling.The discharge capacity of Mn 2 Sb 2 O 7 /RGO reaches 706.72 mAh g À 1 at 200 mA g À 1 after 200 cycles. Even at 1000 mA g À 1 , the capacity loss per cycle of Mn 2 Sb 2 O 7 /RGO is only 0.0344 % for 600 cycles, indicating an excellent high-rate cyclic stability compared to other Sb-based oxides. These results forecast that Mn 2 Sb 2 O 7 /RGO is a potential anode for LIBs, providing a new insight into the selection of high-performance anodes.

“…Such capacity retention is higher than many previously reported SnS 2 nanostructures and their composites (See Table S1 for more comparison). [55][56][57] The XRD patterns of the two electrodes after charge/discharge process revealed that no changes were observed in all the peaks in the pattern can be indexed to VN and SnS 2 ( Figure S7). It should be mentioned that the peak at 20.5 o come from the decomposition of the electrolyte (LiPF 6 ) embedded in the electrode in the air when doing XRD measurement.…”

The vulnerable restacking problem of tin disulfide (SnS2) usually leads to poor initial reversible capacity and poor cyclic stability, which hinders its practical application as lithium ion battery anode (LIB). In this work, we demonstrated an effective strategy to improve the first reversible capacity and lithium storage properties of SnS2 by growing SnS2 nanosheets on porous flexible vanadium nitride (VN) substrates. When evaluating lithium-storage properties, the three-dimensional (3D) porous VN coated SnS2 nanosheets (denoted as CC-VN@SnS2) yield a high reversible capacity of 75% with high specific capacity of about 819 mAh g(-1) at a current density of 0.65 A g(-1). Remarkable cyclic stability capacity of 791 mAh g(-1) after 100 cycles with excellent capacity retention of 97% was also achieved. Furthermore, discharge capacity as high as 349 mAh g(-1) is still retained after 70 cycles even at a elevated current density of 13 A g(-1). The excellent performance was due to the conductive flexible VN substrate support, which provides short Li-ion and electron pathways, accommodates large volume variation, contributes to the capacity, and provides mechanical stability, which allows the electrode to maintain its structural stability.

SnS /graphene composites have attracted extensive attention in energy storage owing to their excellent electrochemical performance. However, most of the previous methods to synthesize SnS /graphene composites require long times, high temperatures, or high pressures, which are obstacles for practical low-cost production. A simple one-pot strategy to prepare SnS /graphene composites has been developed, which is not time-consuming (1 h) and requires moderate temperature (75 °C) in atmosphere. Through this method, ultrafine SnS nanoparticles anchored on graphene nanosheets are prepared and exhibit excellent electrochemical performance for both lithium and sodium storage. Specifically, as anodes for lithium-ion batteries, the SnS /graphene electrode delivers a high capacity of 1480 mAh g after 50 cycles at 0.2 A g . Even at 10 A g , the SnS /graphene electrode can achieve a capacity of 666 mAh g . A constructed full lithium-ion cell exhibits a capacity of 957 mAh g after 50 cycles at 1 A g . This simple one-pot strategy may pave the way for large-scale production and practical application of SnS /graphene composites in energy storage.
