Hydrothermal Synthesis of Molybdenum Disulfide for Lithium Ion Battery Applications
Molybdenum disulfide nanoflakes were synthesized by a simple hydrothermal process using sodium molybdate and thiourea as reactants at a relatively low temperature. X-ray diffraction(XRD) and transmission elec-tron microscopy(TEM) indicate that the samples have the structure of 2H-MoS
2
and the morphology of nanoflakes with the average thickness around 5-10 nm. The results of electrochemical properties indicate that the morphology and size of MoS
2
particles have effects on their capacity when they are used as the anode for lithium ion battery. The as-prepared MoS
2
samples have high reversible discharge capacity up to 994.6 mA·h·g
-1
for the MoS
2
-1 elec-trode and 930.1 mA·h·g
-1
for the MoS
2
-2 electrode and show excellent cycling performances. The MoS
2
-1 electrode has a better cycling stability than the MoS
2
-2 electrode due to their difference in the uniformity of the samples.
