采用微波辅助水热法合成了不同形貌的Li3VO4。结果表明，Li3VO4的晶体大小和形貌由反应溶液中的溶剂类型决定，并讨论了溶剂型效应的可能原因。锂离子电池负极材料Li3VO4的电化学研究表明，材料的形貌和表面性质对其电化学性能有明显的影响。具有多孔结构的Li3VO4纳米晶具有增强的电化学活性，首次放电容量为163mAhg−1。
Li3VO4with various morphologies has been synthesized by a microwave-assisted hydrothermal method. It is shown that the crystal size and morphology of Li3VO4are determined by the type of solvent in the reaction solution and possible reasons of the solvent-type effect are discussed. Electrochemical studies of as-prepared Li3VO4as anode materials for Li-ion batteries demonstrate a clear influence of the materials’ morphology and surface properties on the electrochemical performance. Li3VO4nanocrystals with a porous structure exhibit an enhanced electrochemical activity with an initial discharge capacity of 163 mAh g−1.
