Research Progress of Layered Cathode Materials for Sodium Ion Batteries
In recent years,with the continuous rise in the price of lithium resources,sodium-ion batteries have attracted wide attention due to its rich resources and low price.The performance of sodium-ion batteries mainly depends on the cathode electrode material.The layered transition metal oxide(NaxMO2)cathode electrode material has the advantages of high energy density and good rate performance,but the air stability and cycle stability are poor.Through the strategy of bulk phase doping and surface coating modification,the air stability and structural stability of the material can be greatly improved,making it a cathode electrode material that can meet the needs of power and energy storage battery applications.
