“…As an alternative to the graphite anode, the molybdenum disulfide with a layered graphite-like structure has been extensively investigated because of its high theoretical specific capacity (∼670 mAh·g –1 ), , low price, and abundant reservation. Nevertheless, there are some obstacles to its commercial applications, − such as structural collapse resulting from volume expansion during charge/discharge processes and relatively poor conductivity as a type of semiconductor material.…”

Molybdenum disulfide shows promise as an anode material for lithium-ion batteries. However, its commercial potential has been constrained due to the poor conductivity and significant volume expansion during the charge/discharge cycles. To address these issues, in this study, N-doped MoS 2 /C composites (NMC) were prepared via an enhanced hydrothermal method, using ammonium molybdate and thiourea as molybdenum and sulfur sources, respectively. Polyethylene glycol 400 (PEG400) and polyvinylpyrrolidone (PVP) were added in the hydrothermal procedure as soft template surfactants and nitrogen/carbon sources. The crystal structure, morphology, elemental composition, and surface valence state of the N-doped MoS 2 /C composites were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM), and X-ray photoelectron spectroscopy (XPS), respectively. The results indicate that the NMC prepared by this method are spherical particles with a nanoflower-like structure composed of MoS 2 flakes, having an average particle size of about 500 nm. XPS analysis shows the existence of C and N elements in the samples as C−N, C−C, and pyrrolic N. As anodes for LIBs, the NMC without annealing deliver an initial discharge capacity of 548.2 mAh•g −1 at a current density of 500 mA•g −1 . However, this capacity decays in the following cycles with a discharge capacity of 66.4 mAh•g −1 and a capacity retention rate of only 12% after 50 cycles. In contrast, the electrochemical properties of the counterparts are enhanced after annealing, which exhibits an initial discharge capacity of 575.9 mAh•g −1 and an ultimate discharge capacity of 669.2 mAh•g −1 after 70 cycles. The capacity retention rate decreases initially but later increases and elevated afterward to reach 116% at the 70th cycle, indicating an improvement in charge−discharge performance. The specimens after annealing have a smaller impedance, which indicates better charge transport and lithium-ion diffusion performance.

Molybdenum disulfide (MoS2) is a promising alternative to graphite anodes in battery materials. Therefore, it is critical to scrutinize their structural stability and charge storage capacity during battery operation. In this study, freestanding electrodes consisting of MoS2‐incorporated carbon nanotube aerogels (MSCA) were fabricated using a simple yet scalable hydrothermal method, as used in lithium‐ion batteries. The outer nitrogen‐doped graphitic carbon (NGr) layers support efficient charge transport, even under a substantial compressive environment, and improve the structural integrity, showing significant improvements in battery performance, such as a high rate capacity of 820 mAh g−1 at the current density of 5 A g−1 and 94% capacity retention after 170 cycles (1170 mAh g−1 at 1 A g−1 after 170 cycles), even in the absence of polymer binders and conductive additives. The resulting NGr/MoS2/Single‐Walled Carbon Nanotubes (SWCNT) freestanding electrodes have great potential to increase the volumetric and gravimetric energy density of batteries.This article is protected by copyright.
