Enhanced Li+ conduction in perovskite Li3xLa2/3−x□1/3−2xTiO3 solid-electrolytes via microstructural engineering

To realize all-solid-state lithium batteries, it is necessary to develop solid electrolytes with high ionic conductivity and stability. A total Li⁺ conductivity as high as 4.8 × 10⁻⁴ S cm⁻¹ can be achieved for perovskite Li_3xLa_(2/3)−x□_(1/3)−2xTiO₃ at 25 °C via microstructural modifications.
