Progress in high-voltage MgMn2O4 oxyspinel cathode materials for Mg batteries

Rechargeable magnesium batteries (RMBs) are a promising post-lithium battery technology that demands high-energy density cathode materials with suitable Mg2+ ion intercalation kinetics. In this mini-review, we present challenges and recent developments in the area of high-voltage intercalation MgMn2O4 oxyspinel cathode materials and derivatives, and provide our views on how to overcome some of the remaining obstacles for their realisation in...
