Preparation of  Li1.3Al0.3Ti1.7(PO4)3 Thin Films by Sol-Gel Technique and the Film Characteristics

Abstract

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
