| Abstract: | A new kind of meterial for superionic conductors of Lithium -ionic conductors of Li-type Montmorillonite(MTR:Li+) is studied in this paper. The study result shows that the clectric properties of MTR:Li+ obtained by the authors are following: (1)Ionic conductivity: a.MTR:Li+(PC):σ25℃=1.53×10-3Ω-1cm-1; b.MTR:Li+(DMF):σ25℃=1.31～1.85×10-3Ω-1cm-1; (2)Electronic conductivity:8.8×10-7Ω-1·cm-1; (3)Apparent excit energy:0.14eV; (4)Resolver voltage:2.6—3.3V; (5)Ionic conductivity of MTR:Li+ is of very good time stability,and thmermal and electrochemical properties are satisfectory. |
