Abstract

We report a simple and template-free method for preparing uniform tetragonal-spinel MgMn₂O₄ (T-MgMn₂O₄) hollow spheres, which self-assembled from small sized nanocrystals. The obtained T-MgMn₂O₄ hollow spheres with a micro/nanostructure exhibit excellent rate performance and long cycle life as the cathode for magnesium ion batteries.
