Abstract

Single crystals of NASICON-type material Li_1+xTi_2−xAl_x(PO₄)₃ (LATP) with 0 ≤ x ≤ 0.5 were successfully grown using long-term sintering techniques. Sample material was studied by chemical analysis, single crystal X-ray and neutron diffraction. The Ti⁴⁺ replacement scales very well with the Al³⁺ and Li⁺ incorporation. The additional Li⁺ thereby enters the M3 cavity of the NASICON framework at x, y, z ∼ (0.07, 0.34, 0.09) and is regarded to be responsible for the enhanced Li⁺ conduction of LATP as compared to Al-free LTP. Variations in structural parameters, associated with the Ti⁴⁺ substitution with Al³⁺ + Li⁺ will be discussed in detail in this paper.
