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.
