MgV 2 O 4 is a vanadium spinel considered for rechargeable magnesium ion batteries. Its defect chemistry, solution of dopants, and the diffusion of Mg ions are investigated using advanced atomistic modeling techniques. The energetically most favorable defect is Mg-V anti-site cluster (0.53 eV/defect) assuming that a small percentage of Mg 2+ and V 3+ ions would exchange their positions.
