Abstract
Molybdenum disulfide (MoS2) has emerged as a promising negative electrode due to its excellent capacity in Li-ion- battery applications. The optoelectronic and electrochemical properties of hydrothermally grown MoS2 micro-flower (flakes) have been intensively investigated. Still, the influence of stoichiometric ratio on the electrochemical and optical properties has been largely ignored, especially in Li-ion battery applications. Here, in this context, we systematically vary the stoichiometric ratio of sulfur precursor (Thiourea) in three distinct synthesized MoS2 samples, A1, A2, and A3, via controlled hydrothermal reaction and investigate the associated changes in the electrochemical properties of synthesized MoS2. X-ray photoelectron spectroscopy was employed to measure relative variations in stoichiometry and the existence of MoS2 species. Sample A1 possesses the lowest sulfur content, and it shows a higher specific capacity (2185 mAhg−1) and coulombic efficiency (88.11 %) as an anode material in Li-ion battery application.
