摘要	Li2.7Mg0.3N was synthesized by using a mixture Of Li3N and Mg metal as starting materials. Atomic absorption, XRD and Coulombic titration tests are carried out for the studies on the constitution and properties of Li2.7Mg0.N-3. Atomic absorption analysis reveals the constitution of the sample is Li2.74Mg0.26N. It is shown that Li2.7MgO0.3N has a tetragonal structure with the cell parameters of sample a = 0.388 nm, c = 0.547 nm. The sample's specific capacity is 1695 (mA . h)/g, the maximum of Li+ intercalation is 2.5276; the intercalation fr-ee energy of Li+ DeltaG(in) obtained from the EMF(x) data is -397.51 kJ/mol; the chemical diffusion coefficient of Li+ into Li2.7Mg0.3N is determined to be about 5.90 x 10(-11) similar to 7.23 x 10(-10) cm(2)/s at room temperature and a series of thermodynamic and kinetic parameters is gained. Thermodynamic factor dlna(i)/dlnc(i) is 10.91, ion electrical conductivity sigma (i) is 1.15 x 10(-6) S.cm(-1); component diffusion coefficient D-i is 5.4 x 10(-11) cm(2) - s(-1); ion mobility mu (i) is 2.58 x 10(-9) s(-1) . cm(2) .V-1.
