Hydrothermal synthesis of MnV2O6 nanobelts and its application in lithium-ion battery

Manganese vanadate (MnV2O6) nanobelts with widths of 200-300 nm, thicknesses of 70-90 nm, and lengths up to several micrometers have been successfully synthesized by a simple and facile hydrothermal method without using any surfactants or additives. A phase-transformation promoted splitting mechanism was proposed to understand the formation of the belt-like nanostructures based on the time-dependent experiments. The electrochemical performance of the as-synthesized MnV2O6 nanobelts as anode materials for lithium-ion batteries was investigated by a galvanostatic charge-discharge method. The results showed that the as-synthesized MnV2O6 nanobelts exhibited high capacity and excellent cycle stability, and are thus promising anode candidates in advanced rechargeable lithium-ion batteries.
