Abstract

Lithium superion conductors, Li_3+2x(Sc_1-xMg_x)₂(PO ₄)₃, Li_3-2x(Sc_1-xM_x)₂(PO ₄)₃ (M = Ti, Zr, Sn, Hf) and Li_3-4x(Sc_1-xM_x)₂(PO ₄)₃ (M = Nb, Ta) were prepared by a solid-state reaction. TG-DTA analysis indicated no phase transition in Li_3+2x(Sc_1-xMg_x)₂(PO₄)3 and Li_3-2x(Sc_1-xM_x)(PO₄)₃ (M = Ti, Zr, Sn, Hf) with x higher than 0.05, and in Li_3-4x(Sc_1-xM_x)₂(PO ₄)₃ (M = Nb, Ta) with x higher than 0.025. The room temperature ionic conductivity of Li₃Sc₂(PO₄)₃ has been increased by three orders of magnitude with the highest conductivity observed in Li_3-2x(Sc_1-xTi_x)(PO₄)₃ with x = 0.20 and in Li_3-2x(Sc_1-x Zr_x)₂(PO₄)₃ with x = 0.10. It was ascribed to the stabilization of the high temperature superionic conduction phase and the introduction of vacancies on the Li⁺ sites by substituting Ti⁴⁺ or Zr⁴⁺ for Sc³⁺.
