Abstract NaNi 1/3 Fe 1/3 Co 1/3 O 2 is synthesized by solid-state methods and investigated as a positive electrode material for sodium ion batteries. Galvanostatic cycling of NaNi 1/3 Fe 1/3 Co 1/3 O 2 between 2.0 and 4.2 V provides ~ 165 mAh/g of reversible capacity at C/20. This material also demonstrates great rate-capability and is able to de-intercalate 80 mAh/g even at 30C. First principles calculations are used to determine the order of transition metal oxidation within the system and provide lattice parameters with close proximity to the experimental.
