Abstract
We report the effect of using rutile and anatase TiO 2 as precursors in the synthesis of ceramic Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) NASICON-type electrolyte for solid-state lithium batteries. Anatase TiO 2 enables LATP crystallization at lower temperatures while rutile TiO 2 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.
