The graphite particles with average size of 15 μm were used as the anode base materials forlithium ion battery. Tin oxide was incorporated into graphite particles by a precipitation method. AsSnO2 content increased from 0 to 80 wt%, the initial discharge capacities of SnO2/graphite compositeelectrodes raised from 357 to 688 mAh/g, approaching to their theoretical capacities. The compositeelectrodes exhibited plateau characteristics of SnO2 at 0.85[removed info] 1 V range in the charge voltage-capacitycurves of the first cycle. Increased reversible capacity of the composites suggested that lithium ioncould be stored in the both lattices of tin and graphite. It was demonstrated by XRD that the tin metaldecomposed from tin oxide in the first cycle of charge played a leading role of charge/dischargethereafter
