“…3a shows the XRD pattern of the MoS 2 /C nanospheres. The diffraction peak at 9.9°is attributed to the interlayer spacing of MoS 2 along the c-axis (~0.89 nm) [26,27], consistent with the high-resolution TEM result. An additional peak at 18.3°is also observed, which can be ascribed to the spacing between MoS 2 layer and the carbon layer [28].…”

Developing novel electrode materials for lithium-ion batteries (LIBs) with rapid charge/discharge capability and high cycling stability remains a big challenge to date. Herein, we demonstrate the design and synthesis of ultrathin MoS 2 nanosheets in-situ grown on sponge-like carbon nanospheres by a simple diffusion-controlled process. The unique sponge-like carbon nanosphere core can be used as "reservoir" of electrolyte by adsorbing to shorten the iondiffusion path, and meanwhile as "elastomer" to alleviate the structural change of the MoS 2 nanosheets during the charge/ discharge processes. Furthermore, the vertical ultrathin MoS 2 nanosheets with broadened interlayer space greatly enrich the electrochemical active sites. Consequently, the as-obtained MoS 2 /C nanospheres exhibit increased specific capacities at various rates with superior cycling stability compared to the MoS 2 /C floccules. It is reckoned that the present concept can be extended to other electrode materials for achieving highrate and stable LIBs.

“…However, the MoS 2 flowers and the carbon nanotubes show reversible discharge capacities of only 427.4 and 97.3 mA h g −1 , respectively, and keep only 28 and 64% of the initial capacities after 50 cycles at the current rate of 50 mA g −1 . [117] Kang and co-workers reported a spray pyrolysis approach to synthesize a novel anode material for SIBs consisting of 3D graphene microspheres divided into several tens of uniform nanospheres coated with fewlayered MoS 2 with an expanded interlayer spacing of 0.69 nm. The 3D MoS 2 -graphene microspheres show superior sodium ion storage properties with high rate capability (234 mA h g −1 at 10 A g −1 ) and excellent cycling stability (322 mA h g −1 at 1.5 A g −1 after 600 cycles).…”

Lamellar transition‐metal dichalcogenides (MX2) have promising applications in electrochemical energy storage and conversion devices due to their two‐dimensional structure, ultrathin thickness, large interlayer distance, tunable bandgap, and transformable phase nature. Interlayer engineering of MX2 nanosheets with large specific surface area can modulate their electronic structures and interlayer distance as well as the intercalated foreign species, which is important for optimizing their performance in different devices. In this review, a summary on recent progress of MX2 nanosheets and the significance of their interlayer engineering is presented firstly. Synthesis of interlayer‐expanded MX2 nanosheets with various strategies is then discussed in detail. Emphasis is focused on their applications in rechargeable batteries, pseudocapacitors, hydrogen evolution reaction (HER) catalysis and treatments of environmental contaminants, demonstrating the importance of interlayer engineering on controlling performance of MX2. The current challenges of the interlayer‐expanded MX2 and outlooks for further advances are finally discussed.

A uniformly coated MoS 2 /Carbon-nanocomposite with three-dimensional hierarchical architecture based on carbonized bacterial cellulose (CBC) nanofibers is synthesized by a facile one-step hydrothermal method followed by thermal annealing at 700 °C in Ar atmosphere. Strong hydrogen bonds between the Mo precursor and the BC nanofibers are found to be crucial for the in-situ growth of MoS 2 nanosheets on the nanofibers during hydrothermal process. The unique structure was maintained and the connection between MoS 2 and nanofibers were strengthened in the sintering process, leading to an improved stability of the resulting nanocomposite upon electrochemical cycling. The low-cost and environmentally friendly 3D web-like structure enables binder-free and carbon-free electrodes for lithium-ion batteries, which exhibit high specific discharge capacities up to 1140 mAh/g at the C-rate of 1 C without significant capacity fading for over 50 cycles. The porous conductive hierarchical structure of the composite endows excellent rate performance by avoiding the aggregation of the MoS 2 nanosheets and by accommodating mechanical stress which appears upon electrochemical cycling.
