•A new ternary composite containing SnO2, in-situ formed CuO and graphite nano-sheets was prepared by bead milling.•Wrapping of graphite nano-sheets benefits the reversible formation of SnO2 and CuO in the repeatedly charging process.•SnO2-CuO-graphite nanocomposite anode delivers higher stable capacity than the SnO2-Cu-graphite hybrid.•Wet-phase bead milling is feasible to prepare multi-phase nanocomposite as high performance anode for Li-ion battery.
A ternary nanocomposite of SnO2, CuO and graphite is prepared by bead milling in alcohol, during which the graphite is greatly thinned to form graphite nano-sheets that wrapping the SnO2and in-situ formed CuO nanoparticles. This unique microstructure of SnO2-CuO-graphite nanocomposite benefits the reversible formation of SnO2 and CuO in the repeatedly charging process, and thus significantly improves the cyclic stability and rate capability. The reversible capacity of this ternary nanocomposite remains 561.2 mAh g−1 at 0.1 A g−1 after 150 cycles, much higher than that of the SnO2-graphite, and CuO-graphite hybrids.
