摘要： MnV2O6 nanoribbons were prepared by a simple hydrothermal route. Scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM) confirmed these MnV2O6 single crystalline nanoribbons fabricated along the <200> axis. Electrochemical tests in rechargeable lithium batteries showed that MnV2O6 nanoribbons exhibited a high first discharge capacity of 810 mAhg-1. The crystal structure and local structure of the material during the cycles were studied by X-ray diffraction and Infrared spectrum. The loss of long-range ordering and short-range ordering could be regarded as the important factors for the capacity fading of MnV2O6 as an anode material for Li-ion batteries.
