Influence of Rutile and Anatase TiO2 Precursors on the Synthesis of a Li1.5Al0.5Ti1.5(PO4)3 Electrolyte for Solid-State Lithium Batteries

We report the effect of using rutile and anatase TiO2 as precursors in the synthesis of ceramic Li1.3Al0.3Ti1.7(PO4)3 (LATP) NASICON-type electrolyte for solid-state lithium batteries. Anatase TiO2 enables LATP crystallization at lower temperatures while rutile TiO2 leads to a purer and more crystalline LATP phase. We believe these findings are an important contribution towards the development of more effective and less expensive synthesis of Ti-based solid electrolyte materials.
