The composite material were prepared by sub_micro SnCux, particles depositing on the surface of Carbonaceous Mesophase Spherules(CMS).Electrochemical cycling tests showed that coulombic efficiency of the electrodes prepared by the composite materials was near 100 % after second cycle and the capacity dropped less than 5% after the 30th cycle, versus 390 mAhg-1 special capacity, improving 26 % special capacity of pure CMS electrode. The electrochemical performance of the composite materials is depended strongly on the alloy content in the composite, the addhesive strength between alloy particles and CMS matrix, the distribution of particles on the surface of CMS and the particle size of alloy. The composite material can be applied as the anode of lithium ion batteries.
