Role of Ligand-to-Metal Charge Transfer in Anionic Redox Activity of the Layered Oxide Cathode for Na-Ion Batteries
Developing high-performance cathode materials is crucial for advancing grid-scale sodium-ion batteries (SIBs). Here, we introduce a P2-type layered oxide cathode material, Na0·67Ni0·33Mn0·51Ru0·16O2, which demonstrates exceptional electrochemical performance through a robust dual cationic–anionic redox mechanism.
