Nitrogen　doping　has　been　demonstrated　to　play　a　crucial　role　in　controlling　the　electronic　properties　of　carbon-based　composites.　In　this　paper,　nitrogen-doped　carbon　coated　gamma-Fe2O3　(NC@gamma-Fe2O3)　composite　was　successfully　fabricated　through　a　facile　and　high-yield　strategy,　including　a　hydrothermal　reaction　process　for　porous　gamma-Fe2O3　and　a　subsequent　coating　of　nitrogen-doped　carbon　by　using　dopamine　as　precursor.　The　resulting　composite　combines　the　superior　properties　of　porous　Fe2O3　and　heteroatom-doped　conductive　carbon　layer　derived　from　polydopamine.　When　used　as　the　anode　material　of　the　lithium-ion　battery,　the　as-prepared　NC@gamma-Fe2O3　composite　exhibits　excellent　lithium　storage　properties　in　terms　of　high　capacity,　stable　cycling　performance　(869.6mAh　g(-1)　at　the　current　density　of　0.5　A　g(-1)　after　150　cycles)　and　excellent　rate　capability.
