Nano-sized Sn-Ti alloy anode material prepared by magnetic sputtering was characterized with X-ray diffraction （XRD） and scanning electron microscopy （SEM）. The charge/discharge and cyclic voltammograms of the films electrodes were tested by the high precision battery testing system. The results indicated that the Sn/Ti compound films and Ti/Sn compound films have large difference in performance. Sn/Ti compound films have excellent cycling stability and tolerably high reversible capacity. Its initial discharge specific capacity and charge specific capacity are 9275 mAh/g and 6954 mAh/g, respectively，and the initial capacity fade is 25%. After 30 cycles，specific discharge capacity of 4152 mAh/g was retained and the coulombic efficiency was the same as the value before 30 cycles. This is ascribed to the isolation effect of inactive element Ti between active element Sn and the electrolyte.
