Aerosol deposition method was used as an alternative deposition technique in crystalline electrolyte deposition process. Crystalline Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 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 Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 samples is still needed to make these films more suitable for all‐solid‐state Li‐ion batteries.
