In article number 2001671, Guoying Chen and co‐workers developed a new method to introduce partial fluorine substitution into the oxygen anion sublattice of lithium‐rich cation‐disordered rocksalts. This results in enhanced redox processes of both transition‐metal cations and oxygen anions, enabling more reversible lithium extraction and insertion. Advanced lithium‐ion battery cathode materials with significantly improved performance were obtained.
