FERNANDEZ FERNANDEZ, Néstor; GARCIA SANCHEZ, Mario Fidel; MARINO OTERO, Teobaldo  and  ROMERO IBARRA, Issis Claudette. Synthesis and characterization of the solid ionic conductor La_0.43Ce_0.1Li_0.30TiO₃. Nova scientia [online]. 2013, vol.5, n.9, pp.42-50. ISSN 2007-0705.

The improvement of storing energy devices is an important subject in present days. This paper deals with materials that potentially could be employed as solid electrolytes in secondary lithium batteries. The complex oxide La_0.43Ce_0.1Li_0.30TiO₃ was prepared by a ceramic method. The structural characterization was carried out by X ray powder diffraction and electric properties were analyzed by Electric Polarization in Solid State technique and the Seebeck coefficient calculus. The obtained solids have orthorhombic perovskite-like crystalline structure and they are ionic conductors of lithium ion whereas electronic conduction is absent.

Keywords : Lithium ion conductors; Seebeck coefficient; perovskites; Lithium batteries.
