Hierarchical or mesoporous-structured molybdenum disulfides (MoS2) are promising in lithium-ion batteries (LIBs) thanks to their abundant active sites, fast ion transport, and easy permeation of electrolyte. However, the synthesis of such structures with precise control is challenging, which often requires preliminary preparation of templates or special equipment.1, 2 Herein, hierarchical and mesoporous MoS2 frameworks (HM-MoS2) are synthesized via a phase-segregation method, where ZnS nanoparticles are in situ formed as the hard template. The interconnected channels and mesopores created by etching ZnS enable the conformal carbon coating on HM-MoS2. As an anode in LIB, the HM-MoS2 with an optimal carbon coating delivers a capacity of 396.8 mAh g−1 at 10 A g−1 and a prolonged cycle life with only 2.8 % of capacity decay.
