- 中文摘要: The Li4+xMxSi1-xO4-yLi2O (M=Al, B; x = 0 to 0.6, y = 0 to 0.5) ion conductors were prepared by the Sol-Gel method and examined in detail. The powder and sintered samples were characterized by DTA-TG, XRD, SEM, and AC impedance techniques. The experimental results show that the conductivity and sinterability increased with the amount of excess lithium oxide in the silicate. The Li2O phase acts as a flux to accelerate the sintering process and to obtain high conductivity of grain boundaries. The particle size of the sintered pellets is about 0.25 mm. The maximum conductivity at 200 °C is 5.40 ’ 10-3s.cm-1 for Li4.4Al0.4Si0.6O4-0.3Li2O.
