Highlights: Black-Right-Pointing-Pointer SnO{sub 2} nanoparticles was deposited on ZnO nanoarrays through layer-by-layer assembly. Black-Right-Pointing-Pointer The composite nanowire arrays show improved performance as anode for Li-ion battery. Black-Right-Pointing-Pointer Improved performance was attributed to the combining advantages of each ingredient. -- Abstract: A layer-by-layer approach has been developed to synthesize ZnO/SnO{sub 2} composite nanowire arrays on copper substrate. ZnO nanowire arrays have been first prepared on copper substrate through seed-assisted method, and then, the surface of ZnO nanowires have been modified by the polyelectrolyte. After oxidation-reduction reaction, SnO{sub 2} layer has been deposited onto the surface of ZnO nanowires. The as-synthesized ZnO/SnO{sub 2} composite nanowire arrays have been applied as anode for lithium-ion batteries, which show high reversible capacity and good cycling stability compared to pure ZnO nanowire arrays and SnO{sub 2} nanoparticles. It is believed that the improved performance may be attributed to the high capacity of SnO{sub 2} and the good cycling stability of the array structure on current collector.
