  ABSTRACT: The lithium ionic conductingLa0.45Ce0.1Li0.27TiO3 has been synthesized by sol-gel method. This solid is the result of substitutional doping with Ce(IV) in La0.45Ce0.1Li0.27TiO3 compound. The aim of the replacement of La(III) by Ce(IV) is increase the number of vacancies in the structure and favors the ionic mobility. Structural characterization shows that the obtained material have the expected tetragonal P4/mmm perovskite structure. Chemical analysis shows that composition was homogeneus in all the sample. The bulk conductivity measured at room temperature is about the same as previously reported for its related lanthanum lithium titanate. However, the lower activation energy for ionic conduction encourages further searching for better conductors in this system.
