摘　　要：偏钒酸锰MnV2O6具有特殊的钛铀矿结构,被认为是最有希望成为锂离子电池的负极材料之一.采用溶胶-凝胶法制备出的MnV2O6,对其结构和形貌进行表征,结果表明所制得的样品结晶度高,无杂相,颗粒粒径较均匀.Manganese metavanadate with special brannerite structure was proposed to be the most promising used for the anode of lithium ion batteries. MnV206 was prepared by the sol-gel method, using citric acid as a chelating agent, V205 and Mn（CH3COO）2·4H20 as starting materials. The sample was characterized by X-ray diffraction （XRD）, scanning electronic microscopy （SEM）. The results showed that the nnV206 anode material has high crystallinity, no impurity phase, and well-distributed size of the particles.
