Boosting the Sodium Storage Performance of O3-Type Layered Oxide Cathode by Dual-Site Doping
O3-type layered oxide materials with inherently sufficient Na content have attracted significant attention for sodium-ion batteries (SIBs). However, they suffer from unsatisfactory electrochemical reaction kinetics, irreversible phase transition, and structural degradation during the electrochemical cycling, resulting in poor sodium storage performance. Herein, we propose a Ca/Sn dual-site doping strategy to boost the electrochemical performance of the O3-type layered oxide cathode materials. The synergistic effect of Ca/Sn dual-site doping can modulate the coordination environment and chemical bonds of transition metal (TM) ions, leading to the fast charge transfer kinetics and highly reversible phase transition with a small volume change. The improved structural stability effectively suppresses TM dissolution and maintains particle integrity during long-term cycling. Therefore, Na<sub>0.98</sub>Ca<sub>0.01</sub>Ni<sub>0.33</sub>Fe<sub>0.33</sub>Mn<sub>0.315</sub>Sn<sub>0.015</sub>O<sub>2</sub> delivers superior cycling stability and excellent rate performance. This work highlights the critical role of dual-site doping in enhancing sodium storage performance and provides significant guidance for the design of high-performance cathode materials.
