Tohoku Univ. Technology : Cathode material for rechargeable magnesium batteries : T22-266
Activating disordered rocksalt oxides for cathode materials
Rechargeable magnesium batteries (RMBs) have been developed as post lithium-ion batteries. Previously, only the Chevrel compounds were known to be available as a cathode material for RMBs. However, practical RMBs require cathode materials, which could deliver high capacity with higher electrochemical potential. The present invention provides cathode materials with a disordered rocksalt structure for RMBs. The novel chemical composition of the present material successfully enables reversible and substantial Mg intercalation, which has been previously believed to be difficult, especially in the rocksalt structure. The materials of this patent will expectedly yield cathode materials with higher capacity and electrode potential.
