In recent years, the research of sodium?ion batteries has received more and more attention, and transition metal oxides are considered to be the most potential cathode material system for industrialization due to their easy preparation, low cost, high capacity and high electrochemical activity. As the cathode material of ternary transition metal oxide sodium?ion battery, NaFe1/3Ni1/3Mn1/3O2 further improves the electrochemical performance of cathode materials on the basis of existing monic materials and binary materials. In this paper, the influence of conductive nanomaterial modification on its electrochemical performance was studied using ternary metal oxide NaFe1/3Ni1/3Mn1/3O2 as a model, and a doping strategy was provided to improve the cathode material performance of ternary transition metal oxide sodium?ion batteries.
