Abstract:The magnesium chalcogenide spinel MgSc2Se4 with high Mg‐ion room‐temperature conductivity has recently attracted interest as solid electrolyte for magnesium ion batteries. Its ionic/electronic mixed‐conducting nature and the influence of the spinel composition on the conductivity and Mg2+ migration barrier are yet not well understood. Here, results from a combined experimental and computational study on four MgB2Se4 spinels (B = Sc, Y, Er, Tm) are presented. The room‐temperature ionic conductivities (σion = 2 … Show more
