Enhancing Structure Stability by Mg/Cr Co‐Doped for High‐Voltage Sodium‐Ion Batteries

P2‐Na2/3Ni1/3Mn2/3O2 cathode materials have garnered significant attention due to their high cationic and anionic redox capacity under high voltage. However, the challenge of structural instability caused by lattice oxygen evolution and P2‐O2 phase transition during deep charging persists. A breakth...
