EFFECT OF ZINC SUBSTITUTION ON STRUCTURAL AND IMPEDANCE PROPERTIES OF LAYERED LiNi1/3Co(1/3-x) Mn1/3ZnxO2 (0.05 ? x ? 0.2) CATHODE MATERIALS

The aim of this paper is to study the effect of Zn substituted in place of Co in LiNi1/3Co1/3Mn1/3O2 synthesized by solid state reaction method. A series of materials based on the LiNi1/3Co (1/3-X) Mn1/3 ZnXO2 (0.05 ? x ? 0.2) system were prepared by solid state reaction method and their phase formation processes, crystal structures, impedance and dielThe aim of this paper is to study the effect of Zn substituted in place of Co in LiNi1/3Co1/3Mn1/3O2 synthesized by solid state reaction method. A series of materials based on the LiNi1/3Co(1/3-X) Mn1/3 ZnXO2 (0.05 ? x ? 0.2) system were prepared by solid state reaction method and their phase formation processes, crystal structures, impedance and dielectric were studied by XRD and LCR meter. The X-ray diffraction (XRD) reviles the layered structure of the hexagonal ?-NaFeO2 structure with a space group of . The presence of grain (bulk) effect in the compound was observed. The frequency-dependent electrical data were used to study the conductivity mechanism. An analysis of the electric impedance with frequency at different temperatures has provided some information to support suggested conduction mechanism. ectric were studied by XRD and LCR meter.
