Fan-like MnV2O6 superstructure for rechargeable aqueous zinc ion batteries

In recent years, vanadate has attracted the attention of researchers for its application in electrode materials due to its high specific capacity and layered crystal structure. Herein, a typical manganese vanadium oxides (MnV2O6) product is efficient synthesis via a simple one-step hydrothermal method at 200 °C for 16 h. The as-prepared MnV2O6 sample is found to be the unique one-dimensional fan-like superstructure consist of several nanorods. From a microcosmic point of view, VO6 octahedra sheets are connected by sharing edges which provides highly-open framework for rapid the intercalation and deintercalation of guest ions Therefore, stable MnV2O6 was prepared and used as a cathode material in aqueous zinc ion batteries, which displayed favorable specific discharge capacity, excellent coulombic efficiency and well cycling performance.
