摘要:
A new type of lithium enriched cathode material Li(Li0.05Ni0.6Fe0.1Mn0.25)O-2 was synthesized by sol-gel method with citric acid as a chelating agent. The structural and morphological studies were systematically investigated through X-ray diffraction, SEM with EDS, FT-IR and Raman analyses. The crystallite size of the Li(Li0.05Ni0.6Fe0.1Mn0.25)O-2 cathode material was found to be 45 nm thereby leads to the feasible movement of lithium ion all through the material. FT-IR spectroscopy was used to confirm the metal-oxygen interaction in the prepared cathode material. The electrical properties of the Li(Li0.05Ni0.6Fe0.1Mn0.25)O-2 cathode material were studied by impedance and dielectric spectral analyzes. Li(Li0.05Ni0.6Fe0.1Mn0.25)O-2 showed a maximum ionic conductivity of 10(-6) S/cm at ambient temperature.
