采用水热法制备了不同石墨烯含量的nife2o4 -石墨烯异质结构。作为锂离子电池负极材料的nife2o4 -石墨烯（含石墨烯20%）纳米复合材料具有高达960 mAh g（-1）的高比可逆容量，具有良好的循环稳定性和倍率能力。nife2o4 -石墨烯纳米复合材料优异的电化学性能可归因于其独特的异质结构，使活性材料利用率高，结构稳定性好，电荷输运快。(C) 2012 Elsevier B.V.版权所有
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.
