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. Replacing a portion of the Mn^{4+} with Ti^{4+} alters the chemistry in three profound ways: (1) \u003cb data-path-to-node=\"10,0,0\" data-index-in-node=\"0\"\u003eSuppression of Phase Transitions\u003c\/b\u003e: \u003cspan class=\"math-inline\" data-math=\"Ti^{4+}\" data-index-in-node=\"34\"\u003eTi^{4+}\u003c\/span\u003e (\u003cspan class=\"math-inline\" data-math=\"0.605\\text{ \\AA}\" data-index-in-node=\"43\"\u003e0.605 Å\u003c\/span\u003e) has a larger ionic radius than \u003cspan class=\"math-inline\" data-math=\"Mn^{4+}\" data-index-in-node=\"92\"\u003eMn^{4+}\u003c\/span\u003e (\u003cspan class=\"math-inline\" data-math=\"0.53\\text{ \\AA}\" data-index-in-node=\"101\"\u003e0.53 \u003cspan\u003eÅ\u003c\/span\u003e\u003c\/span\u003e).
