中文摘要：

通过固相法制备了1.5Li2O-P2O5-xTiO2（x=0.1、0.2…0.9）玻璃以及微晶玻璃快离子导体。对制备的玻璃以及微晶玻璃分别进行了交流阻抗和充放电电化学性能等测试。结果表明,1.5Li2O-P2O5-xTiO2微晶玻璃导电率比对应的玻璃导电率要高,最高为1.77×10^-6S/cm,二者的导电率都随TiO2含量的增加而增加,而且1.5Li2O-P2O5-xTiO2微晶玻璃作为锂离子电池负极充放电性能比对应的玻璃充放电性能要好,但是二者总体充放电性能不佳,最高首次放电比容量为283 mAh g^-1。

英文摘要：

1. 5Li2O-P2O5-xTiO2（ x = 0. 1,0. 2,…,0. 9） glass and glass-ceramic fast ionic conductors were synthesized via solid phase method. The electrochemical properties of 1. 5Li2O-P2O5-xTiO2 glass and glass-ceramic were investigated by AC Impedance and charge-discharge. The results show that the electric conductivity of 1. 5Li2O-P2O5-xTiO2glass-ceramic is higher than 1. 5Li2O-P2O5-xTiO2glass（ up to 1. 77× 10^-6S /cm）. The conductivity of 1. 5Li2O-P2O5-xTiO2glass-ceramic is better than 1. 5Li2O-P2O5-xTiO2 glass. The charge-discharge properties of 1. 5Li2O-P2O5-xTiO2glass-ceramic is better than that of 1. 5Li2O-P2O5-xTiO2 glass when used as the anode material for lithium ion battery. But the overall charge and discharge performance of both materials is relatively poor. The highest first discharge specific capacity is283 mAh g^-1.
