A　plum　pudding-like　Fe3O4/Fe/carbon　composite　was　synthesized　by　a　sal　gel　polymerization　followed　by　a　heat-treatment　process　and　characterized　by　X-ray　diffraction,　Raman　spectroscopic　analysis,　thermogravimetric　analysis,　scanning　electron　microscopy　with　energy-dispersive　spectroscopy,　transmission　electron　microscopy,　and　electrochemical　test.　In　this　composite,　uniform　spherical　Fe3O4/Fe　nano-particles　of　about　100　nm　were　embedded　into　carbon　matrix　with　high　monodispersion.　As-prepared　Fe3O4/Fe/carbon　composite　electrode　exhibits　a　stable　and　reversible　capacity　of　over　600　mA　h　g(-1)　at　a　current　of　SO　mA　g(-1)　between　0.002　V　and　3.0　V,　as　well　as　excellent　rate　capability.　The　plum　pudding-like　structure,　in　which　trace　Fe　promotes　conductivity　and　carbon　matrix　mediates　the　volume　change,　can　enhance　the　cycling　performance　and　rate　capability　of　Fe3O4　electrode.　This　unique　structure　is　valuable　for　the　preparation　of　other　electrode　materials.
