Stabilized O3‐Type Layered Oxide Cathode via High‐Entropy Engineering
at 10 C with 49.0% retention) and exceptional cycling stability (80.71% retention after 300 cycles at 1 C; 80.09% after 1000 cycles at 5 C). In situ XRD reveals a highly reversible O3 ↔ P3 ↔ OP2 phase transition sequence, suppressing the irreversible O'3 phase in NFM. These improvements stem from entropy stabilization and synergistic multi-cation effects, demonstrating high-entropy engineering as an effective strategy for developing robust, long-lifespan sodium-ion battery cathodes.
