Hierarchical carbon/MoS2 composites as anodes for advanced electrochemical performance

Many advantages make MoS2 materials as promising anodes for lithium-ion batteries. However, the poor electronic conductivity and slow lithium-diffusion kinetic during the cycles hinder its wide application. In this work, hierarchical carbon/MoS2 composites are successfully prepared using facile hydrothermal method to enhance the electrochemical performance of MoS2 anodes for lithium-ion batteries. The presence of porous carbon could improve the electronic conductivity of the MoS2 anode. In addition, the porous structure could provide rapid transport path for the lithium-ion diffusion. As a result, the as-prepared C/MoS2 composite anode exhibits outstanding cycle performance with reversible capacity of capacity of 789 mAh/g at 0.1 A/g and the high reversible capacity of 602 mAh/g after 300 cycles at 0.5 A/g. This work provides a new method to prepare high-performance anode materials for lithium-ion batteries.
