摘要：

A NiFe2O4-graphene heteroarchitecture with differing graphene content is prepared by a straightforward hydrothermal strategy. The NiFe2O4-graphene (with 20 wt% graphene) nanocomposite as the anode material for lithium-ion batteries shows a high specific reversible capacity up to 960 mAh g(-1) with good cycling stability and rate capability. The superior electrochemical performance of the NiFe2O4-graphene nanocomposite can be attributed to its unique heteroarchitecture, which enables high utilization of active material, good structural stability and fast charge transport.
