Considering collapse in crystalline structure and low diffusion rate of ions during the cycling of O3-NaNi0.5Mn0.5O2 cathode material, a Cu2+-Ti4+ doped NaNi0.4Mn0.4Cu0.1Ti0.1O2 cathode material for sodium-ion batteries was synthesized by adopting a high-temperature solid-state reaction. Effects of doping with transition metal ions (Cu2+ and Ti4+) on the crystal structure, microstructure, and electrochemical performance of NaNi0.5Mn0.5O2 were explored. Results reveal that the NaNi0.4Mn0.4Cu0.1Ti0.1O2 cathode material has a lamellar structure. Within a voltage range of 2-4 V, it delivers an initial discharge specific capacity of 96.7 mAh/g at 0.1C, and presents smooth charge/discharge curves, indicating fewer phase transition for NaNi0.4Mn0.4Cu0.1Ti0.1O2. After 100 cycles at 0.1C, the capacity retention rate remains at 75.5%. In contrast, NaNi0.5Mn0.5O2 cathode material delivers an initial discharge specific capacity of 88.8 mAh/g and retains 61.3% of such capacity under the same testing conditions.
