Summary: In this study, first principle calculations were performed to investigate the properties of LiFePO4 (LFP) cathode material for Li-ion batteries and the effects of Nb doping on its crystalline structure. The results revealed that Nb doping at the Fe site significantly improved the conductivity of LFP, reduced the band gap, and enhanced the stability of the system. Geometrical analysis showed that Nb doping widened the Li passage channel, increased bond length, and reduced covalent strength, leading to a lower energy barrier for Li ion diffusion. Moreover, Nb doping had no adverse effect on the theoretical voltage of LFP. The findings also demonstrated that Nb doping decreased the energy barriers for Li migration and significantly improved the diffusion coefficient of Li-ion in LFP.
