“…The X-ray diffractograms of the anode materials with different composite ratios of MoS 2 /graphite are shown in Figure 1 a, and it can be seen that all four composite anode materials show a crystal structure similar to the intrinsic MoS 2; the diffraction peaks shown in the figure (14.4° (002), 32.7° (100), 39.3° (103), 49.8° (105), and 58.3° (110)) all correspond to the diffraction peaks of the hexagonal crystal structure of molybdenum disulfide [ 20 ]; and the peaks appear in perfect agreement when compared with the standard card PDF # 37-1492. Moreover, the peak positions and peak shapes of all diffraction peaks are clear, indicating that the composite anode material has high crystallinity and purity.…”

Traditional graphite anode material typically shows a low theoretical capacity and easy lithium decomposition. Molybdenum disulfide is one of the promising anode materials for advanced lithium-ion batteries, which possess low cost, unique two-dimensional layered structure, and high theoretical capacity. However, the low reversible capacity and the cycling-capacity retention rate induced by its poor conductivity and volume expansion during cycling blocks further application. In this paper, a collaborative control strategy of monodisperse MoS2/graphite composites was utilized and studied in detail. MoS2/graphite nanocomposites with different ratios (MoS2:graphite = 20%:80%, 40%:60%, 60%:40%, and 80%:20%) were prepared by mechanical ball-milling and low-temperature annealing. The graphite sheets were uniformly dispersed between the MoS2 sheets by the ball-milling process, which effectively reduced the agglomeration of MoS2 and simultaneously improved the electrical conductivity of the composite. It was found that the capacity of MoS2/graphite composites kept increasing along with the increasing percentage of MoS2 and possessed the highest initial discharge capacity (832.70 mAh/g) when MoS2:graphite = 80%:20%. This facile strategy is easy to implement, is low-cost, and is cosmically produced, which is suitable for the development and manufacture of advance lithium-ion batteries.

“…However, it requires multiple complex steps, and thus, the synthesis of the composites is time-consuming. In contrast, the in situ strategy is to form the nanocomposites of MoS 2 and graphene sheets directly through ionic reactions such as chemical vapor deposition (CVD), hydrothermal and solvothermal methods, chemical reduction, and so forth. − As compared with the ex situ approach, the in situ approach has the merit that MoS 2 /graphene composites can be obtained with uniform dispersion and architectures . Although CVD, hydrothermal, solvothermal, and chemical reduction methods are the most popular approaches for composite fabrication, they still possess limitations that need to be addressed.…”

With their similar layered structures and complementary physicochemical properties, molybdenum disulfide (MoS2) and graphene nanosheets can be formed into MoS2/graphene heterostructures with improved electrical, optical, catalytic, and electrochemical properties, enabling promising applications. Here, we present a method to prepare MoS2/graphene nanocomposites by liquid-phase exfoliation through the combined processes of high shear mixing and ultrasonication in deionized water without additional additives, under ambient conditions. MoS2/graphene nanocomposites in large quantities can be achieved with a high-speed mixer homogenizer and a tip sonicator by optimizing the processing parameters for shear exfoliation, such as shearing speed, shearing time, ultrasonication time, and the weight ratio of bulk MoS2 to graphite. Optimum conditions are achieved by comparing the graphene concentration produced, I D/I G, I 2D/I G, and E2g–A1g values from the Raman spectra. This is an easily available and facile method, thereby rendering it an efficient route for large-scale industrial production. We also demonstrate the application of the MoS2/graphene nanocomposites to highly sensitive electrochemical sensors. When used to modify an electrode for electrochemical sensing, the MoS2/graphene nanocomposites exhibit excellent electrochemical performances in the detection of morin.
