摘　　要：本文报道了一种以天然矿物钠基蒙脱石(Montmorillonite.简写 MTR)制备的锂型蒙脱石(MTR:Li+)的离子导电性能。在室温下(25℃),MTR:Li+(Pc)的离子电导率为1.53×10^(-3)Ω^(-1)·cm^(-1),MTR:Li+(DMF)离子电导率为1.31～1.85×10^(-3)Ω^(-1)·cm^(-1),电子电导率在总电导率的1%以下,激活能0.14eV,分解电压2.6—3.3V,电化学性能稳定。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):σ_(25℃)=1.53×10^(-3)Ω^(-1)cm^(-1); b.MTR:Li^+(DMF):σ_(25℃)=1.31～1.85×10^(-3)Ω^(-1)cm^(-1); (2)Electronic conductivity:8.8×10^(-7)Ω^(-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 thmer- mal and electrochemical properties are satisfectory.
