Abstract MoS2-based composites with various hierarchical structures have received tremendous attention owing to their superior lithium storage performance. Herein, a simple synthesis strategy for the construction of hierarchical MoS2/N-doped carbon (MoS2/N–C) nanobelts via a facile hydrothermal method followed by carbonization without any extra assistance of hard templates is reported. The one-dimensional hierarchically mesoporous architecture is assembled by plenty of interlaced nanosheets, which ensures effective Li+ diffusion and good structural stabilization during the electrochemical reaction. Meanwhile, the N-doped carbon closely integrated with MoS2 nanosheets could offer a conductive network for fast electron transport. As a result, the MoS2/N–C nanobelts exhibit a high reversible capacity of 901 mA h g−1 after 100 cycles (at 100 mA g−1), eminent rate capability and cycling performance when used as anode materials for Li-ion batteries. The design concept reported in this work may open a simple avenue to construct hierarchical mesoporous architectures for enhanced lithium storage.
