The　carbon-nanotubes　(CNTs)　/MnOx@　carbon　hybrid　nano-materials　with　1-D　core/shell　architecture　were　fabricated　via　one-step　synthesis,　followed　by　carbonization,　with　CNTs,　KMnO4,　Mn　(CHCOO)2·4H2O,　and　polyvinyl　pyrrolidone　(PVP)　as　the　reactants.　The　nanostructures　and　electrochemical　properties　of　the　CNTs/MnOx@C　material　were　characterized　with　X-ray　diffraction,　scanning　electron　microscopy,　transmission　electron　microscopy,　thermo-gravi-metric　analysis　and　cyclic　voltaminogram.　The　results　show　that　the　CNTs/MnOx@C　composite　may　be　a　good　anode　ma-terial　for　lithium-ion　battery　because　of　its　many　favorable　properties.　For　example,　the　as-synthesized　CNTs/MnOx@C　composite　has　extremely　large　surface　areas,　good　conductivity,　and　high　MnOx　content　up　to　50%.　In　addition,　it　also　exhibits　an　excellent　cycling　stability　of　483.5　mAh/g　after　100　cycles　and　a　good　rate　capability　with　a　specific　capacity　of　368.6　mAh/g　when　cycled　at　a　current　density　of　1000　mA/g.
