| Abstract: | 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 ∼50-nm thick. When cycled in a voltage range between 3.0 V and 4.3 V at 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. |
