摘要

1T metastable state of MoS2 has drawn attention in Lithium-ion batteries (LIBs) due to its superior electronic conductivity and more active sites. In this paper synthesis of 1T-2 H MoS2 using a facile one-step hydrothermal method has been attempted. X-ray diffraction (XRD) confirms the pure MoS2 phase, however, Raman spectroscopy shows the 1T-2 H MoS2 phase with a slight presence of intermediate product MoO3 which is due to the synthesis routes. Scanning Electron Microscopy (SEM) displays the formation of nano-flowers as well as Energy Dispersive X-ray Spectroscopy (EDX) confirms the presence of Mo, and S elements is higher in the ratio in comparison to O element due to the ratio of precursors taken. The as-prepared MoS2 has been tested as an anode material for Lithium-ion Batteries (LIBs). Cyclic Voltammetry (CV) results depict the MoS2 material exhibits excellent stability by tracing the same voltage profile after the initial cycle. Rate performance shows that discharge capacities are about 882.76, 560.02, 442.54, 347.83, 240.35, and 438.70 mAh g− 1 at varied current densities of 100, 200, 500, 1000, 2000, and back to100 mA g− 1 respectively. Galvanostatic charge-discharge performance shows the reversible nature of MoS2 electrodes with high coulombic efficiency (~ 98%) even after 300 cycles.
