Abstract

The Na-ionic layered oxide material has become a research hotspot in recent years due to its low cost,wide resource distribution,high working voltage,high specific capacity and good safety.The main preparation methods of Na-ionic layered oxide cathode materials,the reasons for capacity decay and the modification methods were reviewed.The advantages and disadvantages of common preparation methods and possible causes of capacity decay were analyzed.And the future application and development direction of the cathode materials were prospected as well.
