Abstract
Molybdenum disulfide (MoS2), an inorganic-layered material similar to structure of graphite, was randomly dispersed onto the surface of functionalized multiwalled carbon nanotubes to synthesized nanocomposite MoS2/CNT. The as-obtained product was characterized via SEM, TEM, TGA, X-ray diffraction, and Raman spectroscopies. It was confirmed from XRD that MoS2 layers with interlayer spacing of 0.614 nm were successfully produced. TEM images and Raman spectra indicated a random distribution of 20 nm sized nanoflake MoS2 on the surface of MWNTs. The electrochemical performance of materials are expected to pave the way for the utilized anode material for lithium-ion batteries.
Highlights
For many years, energy storage is a major concern for all businesses and individuals
MoS2 has emerged as a promising anode material in lithium-ion batteries (LIBs) due to its typical-layered transition metal sulfide composing of three stacked atom layers (S-Mo-S)
960 mg of Na2S·9H2O and 50 mg of multiwalled carbon nanotubes (MWNTs) were added into the suspension and dispersed via sonication for 5 min to obtain a precursor solution. 50 mL of ethylene glycol was mixed with the precursor solution, and the reaction was carried out at 80°C for 30 min under stirring with gradual dropping of 2 mL of 1 M HCl solution
Summary
Energy storage is a major concern for all businesses and individuals. Many methods are developed to capture renewable energy sources such as solar cells, wind turbines, and tidal power. The conversion of these energy sources into direct electricity does not meet the demand for production and consumption. The emergence of rechargeable batteries in general and lithium-ion batteries (LIBs) in particular has become an effective alternative to battery research. In landscape of LIBs, transition metal dichalcogenide (TMD), especially molybdenum disulfide (MoS2), has currently attracted considerable attention due to its important role in many applications. MoS2 has emerged as a promising anode material in lithium-ion batteries (LIBs) due to its typical-layered transition metal sulfide composing of three stacked atom layers (S-Mo-S)
