在结晶电解质沉积工艺中，采用气溶胶沉积方法作为替代沉积技术。采用X射线衍射、扫描电子显微镜、透射电子显微镜和交流阻抗技术，在不锈钢基体上成功地制备了Li1.3Al0.3Ti1.7（PO 4）3厚膜.沉积膜的密度在理论密度的83%和86%之间，并且计算出维氏硬度具有在260和280 Hv之间的值。体电导率和总电导率分别为3.62 × 10−3和1.12 × 10−6 S/cm，直流电导率<10−10 S/cm。Li1.3Al0.3Ti1.7（PO 4）3样品的总电导率仍然需要改进，以使这些薄膜更适合于全固态锂离子电池。
Aerosol deposition method was used as an alternative deposition technique in crystalline electrolyte deposition process. Crystalline Li1.3Al0.3Ti1.7(PO4)3 thick layers were successfully deposited on stainless-steel substrates and X-ray diffractometry, scanning electron microscopy, transmission electron microscopy, and AC impedance techniques were used to characterize these films. The density of the deposited films was between 83% and 86% of the theoretical density and Vickers hardness was calculated to have values between 260 and 280 Hv. Bulk and total conductivities were 3.62 × 10−3 and 1.12 × 10−6 S/cm, respectively, and DC conductivity was <10−10 S/cm for a wide range of film thicknesses. Improvement in total conductivity of the Li1.3Al0.3Ti1.7(PO4)3 samples is still needed to make these films more suitable for all-solid-state Li-ion batteries.
