    More than three times higher bulk density, easy to handle in air, and high abundance on earth crust make magnesium metal a desirable element in battery application. Several efforts have been attempted to construct the rechargeable magnesium-ion battery, unfortunately none of them are successful to a limit. Here, a new generation of vanadium oxide linked with ammonium ions is considered an active cathode for magnesium ion insertion. The Zr doped-NH4V4O10 (Zr-NVO) nanorod exhibits an initial discharge capacity of 328 mAh g−1 at 40 mA g−1 current density with negligible capacity fading till 150 cycles. The estimated Mg2+ diffusivity in such cathode is found to be in the range of 10−11 to 10−12 cm2 s−1, demonstrating a pronounced Mg-ion mobility in Zr-NVO cathode. In addition, a detailed mechanistic study is performed at different states of charge using XRD, XPS and in-situ XANES analysis. In conclusion, to achieve the ultimate goal of such study, a full-cell is assembled and evaluated by coupling tin anode with magnesiated Zr-NVO cathode. The cell has been cycled for a limited number of cycles and the reason behind the limited cycling behaviour is discussed and offers us a pathway to a resolution of the problem for rechargeable magnesium-ion battery development in the near future.
