| 中文摘要 | A well-organized flexible interleaved composite of graphene nanosheets (GNSs) decorated with Fe(3)O(4) particles was synthesized through in situ reduction of iron hydroxide between GNSs. The GNS/Fe(3)O(4) composite shows a reversible specific capacity approaching 1026 mA h(-1) g(-1) after 30 cycles at 35 mA g(-1) 580 mAh g(-1) after 100 cycles at 700 mA g(-1) as well as improved cyclic stability and excellent rate capability. The multifunctional features of the GNS/Fe(3)O(4) composite are considered as follows: (i) GNSs play a "flexible confinement" function to enwrap Fe(3)O(4) particles, which can compensate for the volume change of Fe(3)O(4) and prevent the detachment and agglomeration of pulverized Fe(3)O(4), thus extending the cycling life of the electrode; (ii) GNSs provide a large contact surface for individual dispersion of well-adhered Fe(3)O(4) particles and act as an excellent conductive agent to provide a highway for electron transport, improving the accessible capacity; (iii) Fe(3)O(4) particles separate GNSs and prevent their restacking thus improving the adsorption and immersion of electrolyte on the surface of electroactive material; and (iv) the porosity formed by lateral GNSs and Fe(3)O(4) particles facilitates ion transportation. As a result, this unique laterally confined GNS/Fe(3)O(4) composite can dramatically improve the cycling stability and the rate capability of Fe(3)O(4) as an anode material for lithium ion batteries. |
