Abstract

Abstract:

In order to improve the performance of LiNiO₂，Nb-doped LiNiO₂was prepared by a solid-state reaction method.The effects of the amount of Nb-doping on the structure and performance of LiNiO₂ were investigated by X-ray diffraction analysis（XRD），galvanostatic titration（GITT），electrochemical impedance spectroscopy（EIS） and other methods.Nb-doping could effectively improve the order degree of the layered structure，reduce Li⁺/Ni²⁺ mixing，reduce the charge transfer impedance，and increase the diffusion coefficient of Li⁺ in the active materials.Therefore，LiNi_0.99Nb_0.01O₂ exhibited higher capacity retention（91.4% after 100 cycles at 0.5C） and better rate capability（143 mA·h/g at 5C）.As a comparison，the data of bare LiNiO₂ was 69.2% and 127 mA·h/g under the same conditions.These results further demonstrated that Nb-doping with a strong Nb—O bond，high valence stat，and larger ionic radius could effectively improve the performance of LiNiO₂.
