lattice stabilization through cation ordering and highlight the necessity of co-optimizing doping content with synthesis temperature. This work revises the conventional understanding of high-valence doping mechanisms by establishing cation ordering as the primary factor for stability, providing a generalizable principle for designing next-generation ultra-high-nickel cathodes.
