摘　　要：Among the large energy storage batteries,the sodium ion batteries(SIBs)are attracted huge interest due to the fact of its abundant raw materials and low cost,and has become the most promising secondary battery.Tunnel-type sodium manganese oxides(TMOs)are industrialized cathode materials because of their simple synthesis method and proficient electrochemical performance.Na_(0.44)MnO_(2)(NMO)is considered the best candidate material for all tunnel-type structural materials.In this paper,the research progress in charge and discharge of cathode materials for tunnel-type structural SIBs is reviewed,the redox mechanism and all sorts of synthesis methods and different coating methods lead to different morphology and electrochemical properties of materials and the classification of electrolytes and nonaqueous electrolytes.The development and utility of aqueous solutions are discussed,and the mechanism is analyzed.Summarized the cationic potential of the transition metal oxide for tunnel structure,plays a vital role in predicting and designing the cathode material of this structure.In addition,the future opportunities and challenges for such tunnel-type SIBs in this field are described in detail.
