Dispersed spherical Fe 3 O4 nanoparticles were synthesized by a hydrothermal method. The influences of odecyl trimethyl ammonium bromide（DTAB） concentration on the morphology and particle size of the as-prepared Fe3 O4 were studied. Electrochemical performance of the as-prepared sample as anode materials of lithium ion battery was investigated. It is found that the as-prepared sample exhibits superior rate performance and cycle performance. The nano-sized materials provide structural stability and favor the transfer of lithium ions.
