Abstract

This paper reports the use of a rheological phase reaction method for preparing MoS₂ nanoflakes. The characterization by powder X-ray diffraction indicated that MoS₂ had been formed. High resolution electron microscopy observation revealed that the as-prepared MoS₂ nanoflakes had started to curve and partly form MoS₂ nanotubes. The lithium intercalation/de-intercalation behavior of as-prepared MoS₂ nanoflake electrode was also investigated. It was found that the MoS₂ nanoflake electrode exhibited higher specific capacity, with very high cycling stability, compared to MoS₂ nanoparticle electrode. The possible reasons for the high electrochemical performance of the nanoflakes electrodes are also discussed. The outstanding electrochemical properties of MoS₂ nanoflakes obtained by this method make it possible for MoS₂ to be used as a promising anode material.
