By adjusting the transition metal ratio from the symmetric 1:1:1 (Ni1\/3Fe1\/3Mn1\/3) mix to a slightly higher nickel and manganese content relative to iron, this composition seeks to optimize the balance between energy density, phase stability, and air stability during cycling.\u003c\/p\u003e\n\u003cdiv style=\"text-align: left;\"\u003eAltering the transition metal stoichiometry fundamentally changes the electrochemical behavior of the final sodiated cathode: (1) \u003cstrong\u003eNickel (Ni}^{2+} Enrichment (40%)\u003c\/strong\u003e: Increasing nickel content expands the initial capacity of the material.

(2) \u003cstrong\u003eIron (Fe^{3+)) Reduction (20%)\u003c\/strong\u003e: Lowering the iron ratio to 20% mitigates the structural distortion and rapid capacity decay associated with the collective Jahn-Teller effect of high-spin Mn^{3+} formed through charge transfer with iron, while still keeping material costs low.
