用溶胶凝胶法合成了Ｌｉ２Ｓｉ２Ｏ５ＸＬａ２Ｏ３（Ｘ＝０～９％）复合电解质，与传统的固相合成方法相比，发现该法可使样品的合成温度降低，其离子导电性得到提高，并研究了分散第二相Ｌａ２Ｏ３对Ｌｉ２Ｓｉ２Ｏ５离子导电性的影响
Li2Si2O5XLa2O3 (X = 0 ~ 9%) composite electrolyte was synthesized by sol-gel method. Compared with the traditional solid-phase synthesis method, it was found that this method can reduce the synthesis temperature of the sample and improve the ionic conductivity. Effect of dispersed second phase La2O3 on ionic conductivity of Li2Si2O5
