Abstract: Cu/Ni co-doped P2 phase Na_0.67Fe_0.1Mn_0.9O₂sodium-ion battery layered oxide anode materials were successfully synthesized by sol-gel method, and the effects of co-doping on the morphology and electrochemical properties of the layered oxides were investigated.The results show that the surface of the Cu/Ni co-doped materials is smoother and the layer structure is clearer, and the long cycle stability and the multiplicity performance at high current density of the four doped materials are also improved compared with the undoped materials.Among them, Na_0.67Fe_0.1Mn_0.75Cu_0.05Ni_0.1O₂ has a capacity retention rate of 92.2% after 50 cycles of charge/discharge, and still has a capacity retention rate of 87.2% after 100 cycles, and the capacity of the material is only 10.26% depleted after a multiplicative cycling of 0.1C-0.5C, which shows an excellent electrochemical performance.
