In this work, hierarchical MoS₂/C quasi-hollow microspheres are prepared by a one-pot hydrothermal process with the addition of glucose. The glucose is not only inclined to form the roundish sphere in the completion of the synthesis of MoS₂, but at the same time the microspheres formed by the glucose can act as the nuclei on which the MoS₂ grows. Glucose, acting as a nucleating agent, has the advantages of being low-cost and environmentally friendly, which can simplify the fabrication process. The interiors of the MoS₂/C samples are multi-hole and quasi-hollow, which is beneficial for the insertion and extraction of lithium ions. For the first time, we demonstrate that hierarchical-structured MoS₂/C quasi-hollow microspheres exhibit an excellent cycling stability and rate capability in lithium ion batteries (LIBs) and are significantly superior to the bulk MoS₂. The method presented in this article may provide a simple, clean. and economical strategy for the preparation of MoS₂/C microspheres as a feasible and promising anode material for LIBs.
