Preparation and Lithium Storage Properties of Hierarchical Hydrangea‐Like MoS2/C Composites

In this article, hierarchical hydrangea‐like MoS2/C composites are synthesized through a simple one‐pot solvothermal method followed by heat treatment for the first time. The morphology and electrochemical performance of MoS2/C are largely affected by the solvent composition and carbon content during the solvothermal process. The interlayer distance of few‐layer MoS2 is increased by the insertion of carbon layer for the unique hierarchical hydrangea‐like MoS2/C nanostructure. The cycling performance of MoS2/C is greatly improved because it takes advantage of both good conductivity and structural stability. When tested as an anode of a lithium‐ion battery, the results show that the reversible specific capacity of the MoS2/C electrode is 853.1 mAh g−1 after 80 cycles at a current density of 200 mA g−1 with capacity retention of 98.4%. Especially, when tested under 500 mA g−1, the reversible specific capacity can reach to 780.6 mAh g−1 after 200 cycles.
