Ultrasmall Fe₂O₃ nanoparticles/MoS₂ nanosheets composite as high-performance anode material for lithium ion batteries.

ABSTRACT: Coupling ultrasmall Fe₂O₃ particles (~4.0 nm) with the MoS₂ nanosheets is achieved by a facile method for high-performance anode material for Li-ion battery. MoS₂ nanosheets in the composite can serve as scaffolds, efficiently buffering the large volume change of Fe₂O₃ during charge/discharge process, whereas the ultrasmall Fe₂O₃ nanoparticles mainly provide the specific capacity. Due to bigger surface area and larger pore volume as well as strong coupling between Fe₂O₃ particles and MoS₂ nanosheets, the composite exhibits superior electrochemical properties to MoS₂, Fe₂O₃ and the physical mixture Fe₂O₃+MoS₂
