Abstract

In this work series of LiNiyCo1−yPO4 (y=0, 0.2, 0.4, 0.6, 0.8 and 1) phospho olivines were synthesized by solution co-precipitation technique and characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) and impedance spectroscopic analysis. The XRD patterns of LiNiyCo1−yPO4 (y=0.2, 0.4, 0.6 and 0.8) revealed that they are essentially single phase and have an Olivine-type XRD patterns similar to those of their parent compounds LiCoPO4 and LiNiPO4. An increase in wave number for most of the dominant infrared bands in PO4 vibrational region for the substitution of Co by Ni in LiCoPO4 indicated the strengthening of both the P-O and Li/Ni-O bonds.
