Impact of Fluorine Content on Structure, Redox, and Electrochemical Performance of Disordered Rock-Salt Li1.25Mn0.5+ y /2Nb0.25– y /2O2– y F y Electrode Materials

Abstract Disordered rocksalt (DRS) oxides are highly promising positive electrode materials for next-generation Li-ion batteries, yet their practical application is severely bottlenecked by the irreversibility of oxygen-redox processes. Fluorination (O2– by F– substitution) repre...
