It evolved directly from the classic Na0.67Ni0.33Mn0.67O2 baseline to solve the severe structural degradation that occurs at high operating voltages.\u003c\/p\u003e\n\u003cp\u003eIn the pristine Na0.67Ni0.33Mn0.67O2 matrix, charging the battery above 4.0 V (vs. Na\/Na+) extracts a large amount of Na+ ions. This triggers a highly destructive P2 to \"O2\" (or OP4) phase transition, causing the layers to glide, the crystal lattice to abruptly contract, and the cycle life to plummet.
