Abstract

A unique hierarchical hollow-nanostructure consists of ultrathin MoS2 nanosheets and hollow MoO2 nanospheres has been designed as anode material for lithium batteries. And a simple process for producing ultrathin MoS2 nanosheets in-situ grown on hollow MoO2 nanospheres is reported. Such a hierarchical nanostructure has four advantages: Firstly, the high electric conductivity of the MoO2 core can effectively increase the performance of the composite. Secondly, the shell of MoS2 nanosheets with highly exposed active sites can improve the electrochemical reaction activity of this heterostructure. Thirdly, the reciprocal hybridization between the MoO2 core and MoS2 shell can availably prevent the aggregation of MoS2 nanosheets. Owing to the unique hierarchical MoO2@MoS2 hollow-nanostructure, it exhibits great electrochemical performance and can deliver reversible capacity as high as 820.7 mA h g−1 at a current density of 0.5 A g−1 after 100 cycles, while it is used as a new anode material for lithium-ion batteries.
