摘要：

In this work, we have synthesized monoclinic Li3V2(PO4)(3) nanobelts via a single-step, solid-state reaction process in a molten hydrocarbon. The as-prepared Li3V2(PO4)(3) nanoparticles have a unique nanobelt shape and are similar to 50-nm thick. When cycled in a voltage range between 3.0 V and 4.3 Vat a 1C rate, these unique Li3V2(PO4)(3) nanobelts demonstrate a specific discharge capacity of 131 mAh g(-1) (which is close to the theoretical capacity of 132 mAh g(-1)) and stable cycling characteristics.
