Abstract A novel hierarchically N-doped carbon coated MoS2 microflower assembled with nanosheets is synthesized via a SiO2-templete assisted hydrothermal method. Differing from the traditional synthesis mechanism of the similar micro-/nanostructure, the wrinkled 2D MoS2 grains grow in the pore of the assembled SiO2 aggregates with squeezing action. In the designed macro-/nanostructure, the interconnected network of carbon coated nanosheets increases surface area and decreases transfering resistance for ions and electrons, which is beneficial to conductivity and total electrode capability. The self-supported structure alleviates volume change and improves cycling stability. This synthesized MoS2@NC exhibits high capacity and remarkable cycling stability. It shows initial capacity of 1103.6 mAh g−1 and maintains a reversible capacity of 786.4 mAh g−1 after 50 cycles at 0.1 A g−1.
