Abstract

Single-phase LiNiPO₄ and doped and coated LiNiPO₄ particles were synthesized by solid-state reaction method. The electrochemical properties of LiNiPO₄/Li₄Ti₅O₁₂ batteries were analyzed by cyclic voltammetry (CV) and charge/discharge tests. The structural and morphological performance of LiNiPO₄ and doped LiNiPO₄ particles were investigated by X-ray diffraction (XRD), scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR). The results show that the electrochemical properties of doped LiNiPO₄ have been improved.
