In this study, advanced electrode material Na0.7MnO2.05 with a diameter of 2 mu m and Na content of 5% was prepared by the solid phase method. After sintering at 800 degrees C, Na0.7MnO2.05 demonstrated strong electrochemical performance as the cathode material of a sodium-ion battery, with an initial capacity of 157.67 mAh g(-1) and a capacity retention of 79% after 50 cycles. The excellent electrochemical properties were attributed to the appropriate calcination temperature, which improved the conductivity and stability of the Na0.7MnO2.05 material.
Advanced electrode materials play an important role in the development of methods for large-scale production of sodium-ion batteries. In this paper, Na0.7MnO2.05 with a diameter of 2 mu m and Na content of 5% was prepared by the solid phase method. As the cathode of a sodium-ion battery, Na0.7MnO2.05 exhibits strong electrochemical performance after sintering at 800 degrees C. At 0.1 C, the initial capacity of NMO is 157.67 mAh g(-1) with a capacity retention of 79% after 50 cycles. The excellent electrochemical properties are attributed to the appropriate calcination temperature, which improves the conductivity and stability of the Na0.7MnO2.05 material.
