英文摘要	the present paper reports a facile method to synthesize cnt-fe2o3 and cnts-fe3o4@c beaded structures by deposition of fe2o3 and carbon layers on cnts, which integrate both electronic conductivity and buffering matrix design strategies. the cnt-fe2o3 and cnts-fe3o4@c were tested as anode materials for lithium-ion batteries, cnt-fe2o3 showed excellent cycling performance, the reversible capacity retention after 80 cycles is stable at 410 ma h g(-1). however, cnts-fe3o4@c exhibited improved reversible capacity and better cycling performance when compared to cnt and cnts-fe2o3. the highly improved reversible capacities are attributed to the combination of (a) the network structured cnts, which improve the matrix electrical conductivity, (b) the mesopores created by the carbon coating on fe3o4 nanoparticles and cnts, which increases lithium-ion mobility and storage, and (c) the fe3o4 nanoparticles attached to the cnts facilitate the transport of electrons and shorten the distance for li+ diffusion. this study provides a cost-effective, highly efficient method to fabricate nanomaterials which combines carbon nanotubes with iron oxide nanoparticles for the development of lithium ion batteries with high-performance.
