However, their advancement critically relies on the development of cathode materials that simultaneously deliver high-rate capability and long-term cycling stability. Although the conventional P2-Na0.67Ni0.33Mn0.67O2 cathode exhibits high energy density, its structural degradation at elevated voltages compromises long-term reliability in high-power applications.

To address this challenge, this work propose a multi-element doping strategy, designing a P2-Na0.67Zn0.05Ni0.23Fe0.1Mn0.57Ti0.05O2 cathode material. This novel composition effectively suppresses high-voltage phase transitions, thereby enhancing structural stability. Electrochemical performance tests reveal that the optimized cathode retains >85% capacity retention after 300 cycles at a high rate of 3C, demonstrating exceptional rate capability and cycling durability. This work provides a rational design strategy for developing high-performance cathode materials in power-type Na-ion batteries. The work titled \u201cHigh-Rate and Long-Cycling P2-Type Cathode Material for Na-Ion Batteries<\/a>\u201d, was published on Acta Physico-Chimica Sinica<\/a> (published on Nov. 1, 2025).
