文摘

The molybdenum disulfide/carbon (MoS₂/C) microsphere composite is synthesized by a facial hydrothermal method using carbon spheres as a template. The structure and morphology of the expected compounds are characterized by x-ray diffraction, x-ray photoelectron spectroscopy and scanning electron microscopy techniques. The electrochemical properties of the composite are investigated by a battery testing system. The as-prepared MoS₂/C composite has an initial discharge capacity of 943 mAh g−1 and retained a reversible capacity at 705 mAh g−1 after 165 cycles with nearly 100% coulombic efficiency, exhibiting better electrochemical performances than those of pure MoS₂. The MoS₂/C composite is a promising anode material for lithium-ion battery applications.
