| Abstract: Lithium solid electrolytes of Li9-nxMn+xN2Cl3(M=Li+,Na+,Mg2+,Al3+) were prepared. The ionic conductivities of prepared samples have been determined from room temperature to 623 Kby PAR368-1 AC-impedance spectrometer. The frequency measurement varies from 4Hz to 100KHZ. The structure of samples was identified by X-ray diffraction. Decomposition voltage and electronic conductivities of Li9-nxMn+xN2Cl3 have also been determined. The conductivity of Li9-nxMn+xN2Cl3 depends on the ionic radius and valence of substitution ion. When x=0.05 ,the experimental result showed that the maximum conductivity of Li9-nxMn+xN2Cl3 was obtained. |
