Abstract:
Li2Si2O5-XLa2O3(X= 0~9%) composite electrolytes have been prepared by Sol-Gel method. Compared with the samples by the conventional solid state reaction, the experimental results show that this method need lower temperature and present higher ionic conductivity. The effects of dispersed second phase La2O3 on the ionic condutivity of α-Li2Si2O5 are studied in this paper.
