摘要/Abstract

摘要：采用溶液沉积法制备Li_1.3Al_0.3Ti_1.7(PO₄)₃薄膜，用X射线衍射、扫描电子显微镜检测和分析薄膜的物相及表面形貌，采用循环伏安检测不同条件下制备的Li_1.3Al_0.3Ti_1.7(PO₄)₃薄膜的电化学窗口，采用电流检测仪测定薄膜的电子绝缘性能.研究表明该法制备的Li_1.3Al_0.3Ti_1.7(PO₄)₃薄膜结晶性良好，薄膜均匀、致密、无龟裂，薄膜的电化学窗口为2.4V，电子电导率的数量级为10^-11 S/cm，薄膜具有较宽的电化学窗口和良好的电子绝缘性.

关键词： 锂离子, 薄膜, 电化学, 循环伏安

Abstract: Solid electrolyte of Li_1.3Al_0.3Ti_1.7(PO₄)₃thin films were prepared by sol-gel technique.The phase identification and surface morphology were investigated by X-ray diffraction and scanning electron microscopy.Electrochemical window and electronic insulating properties were examined by cyclic voltammetry and current testing instrument.The results show that the films with good crystallinity are homogeneous,dense and crack-free.The electrochemical window is more than 2.4V,and the electronic conductivity is 10^-11 S.cm^-1.The film possesses wide electrochemical window and good electronic insulating.

Key words: lithium ion, thin films, electrochemistry, cyclic voltammetry
