摘要

A novel TiO2(B) nanowires/carbon nanotubes (TNWs/CNTs) nanocomposite was designed andobtained via a simple hydrothermal reaction. The nanocomposites exhibit unique feature of TiO2(B)nanowires twined with CNTs. The addition of CNTs can increase the electrolyte/electrode contact areaand improve the electrical conductivity. Comparing with pure TNWs, the TNWs/CNTsnanocomposites have greatly improved rate capability, it demonstrate high capacity of 355.9, 291.4, 263.8, 235.7 and 191.3 mAh.g , at current rate of 0.2, 0.5, 1, 2 and 5 C, respectively, and the capacityretention ratio is up to 90%. The results suggest the unique nanostructure and highly conductive carbonnanotubes induce excellent electrochemical performance of TNWs/CNTs nanocoposites, and make it apromising anode candidate for lithium-ion batteries (LIBs).
