Mg–substituted Na3Ni2–xMgxSbO6 cathode materials are synthesized via a scalable high–temperature solid–state method to improve the cyclability of the honeycomb–layered oxide cathode in sodium–ion batteries. Here, the partial substitution of Ni2+ by Mg2+ in the transition–metal layer suppresses the electrochemically unfavorable P3–O1 transition and enlarges the lattice parameters to bring improved performance with respect to capacity retention, Coulombic efficiency, and Na (de)intercalation kinetics.
