Impacts of precursor solution recipe, processing parameters, and pellet thickness on the lithium ionic conductivity of the ceramic materials with perovskite structure of Li_0.3La_0.57TiO₃ were investigated and new method was proposed to synthesize Li_0.3La_0.57TiO₃ solid state electrolyte. The results showed that ionic conductivity of Li_0.3La_0.57TiO₃ membrane which was synthesized by firstly forming colloidal TiO₂ (i.e., TiO₂ sol) and then Li⁺ and La⁺ were added to the colloidal TiO₂ was on the order of 10^-5 S/cm. It also showed that the temperatures corresponding to a full decomposition for L_0.3La_0.57TiO₃ is about 750°C and materials start forming perovskite structure when temperature reaches about 900°C and the lithium ionic conductivity gains about 21% increase when the pellet thickness is reduced to about ¼
