摘要:
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 SnO2 and 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.
