摘要：

A V2O5 nanobelt array has been designed and prepared on a conductive substrate for the first time. The synthesis strategy is based on the hydrogen bonding action between the functionalized surface of a Ti substrate and the earlier-formed V2O5 center dot xH(2)O nanoseeds, and 1-dimensional (1-D) growth property of V2O5 center dot xH(2)O. The as-prepared V2O5 nanobelt array exhibits a greatly enhanced performance in Li-ion batteries as the cathode and anode; meanwhile, the enhancement mechanism is presented, which is not only important to design functional materials in Li-ion batteries, but also extendable to other systems' design and fabrication.
