High stability Na0.7MnO2.05 cathode for sodium ion batteries

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.
