Lithium-ion solid electrolyte disc with high conductivity even at low temperature for electrochemical devices were designed using Li_1+x+yAl_xGa_yTi_2-x-y(PO₄)₃ (x + y = 0–0.5) with NASICON-type structure. The solid-electrolyte discs were synthesized by a solution method at 900–1000 °C. Effects of Al and/or Ga dopants and crystal structures on ionic conductivity of the solid electrolytes were investigated. Almost single phase of Li_1+x+yAl_xGa_yTi_2-x-y(PO₄)₃ (x + y = 0–0.5) systems could be synthesized at sintering temperatures above 900 °C up to x = 0.5, y = 0.25. An ionic conductivity as high as 9.3 × 10⁻⁴ S/cm at 30 °C and activation energy of 0.29 eV were obtained with the trivalent-cation double-doped Li_1.5Al_0.25Ga_0.25Ti_1.5(PO₄)₃ disc sintered at 900 °C.
