摘要
MoS2/C nanocomposites were synthesized by a facile hydrothermal route employing sulfocarbamide, sodium molybdate and D-grouse as starting materials. XRD analysis showed that the MoS2 was a two-dimensional nanosheet crystal and C was retained as amorphous after their calcinations at 800 degrees C. TEM images showed that MoS2 was uniformly dispersed in the amorphous carbon. The MoS2/C Composites exhibited high reversible capacity and excellent cyclic performance when used as Li-intercalation electrodes. The improvements in electrochemical performance are attributed to the incorporation of amorphous carbon, which can suppress the aggregation and pulverization of active materials, and keep the active materials electrically connected.
