Abstract

A Li_0.17La_0.61TiO₃(111)/LiMn ₂O₄(111) solid electrolyte/electrode hetero-epitaxial system with applications in all solid-state batteries has been synthesized on a SrRuO₃(111)/SrTiO₃(111) substrate using pulsed laser deposition. XRD patterns provided evidence for the epitaxial growth of Li _0.17La_0.61TiO₃(111) on LiMn₂O ₄ at a low deposition temperature of 750 °C. X-ray reflectivity analysis confirmed that the low temperature deposition resulted in intimate contact between LiMn₂O₄ and Li_0.17La _0.61TiO₃, although small amounts of oxygen and titanium were found to have diffused between the materials. The Li_0.17La _0.61TiO₃/LiMn₂O₄ film exhibited reversible electrochemical activity between 3.0 and 4.5 V. No significant structural changes were observed in the cycled film, indicating that the Li _0.17La_0.61TiO₃/LiMn₂O₄ interface is chemically and electrochemically stable during the battery reaction. The integration of electrode and solid electrolyte oxides in epitaxial multi-layer structures is expected to allow the design of new configurations for all solid-state batteries.
