Abstract
Garnet-type solid electrolytes Li 7 La 3 Zr 2 −  x Mg 2 x O 12 , Li 7 La 3 Zr 2 − 0.75 x Sc x O 12 and Li 7 − 2 x Zn x La 3 Zr 2 O 12 with x  = 0, 0.025, 0.05 and 0.1 were synthesized at 1075 °C by using the traditional solid-state reaction method. It is found that substitution of Mg 2 + and Sc 3 + for Zr 4 + is more effective in improving the Li 7 La 3 Zr 2 O 12 (LLZ)'s densification and ionic conductivity than the substitution of Zn 2 + for Li + . As a result, the highest room-temperature total conductivity and the lowest activation energy are obtained in LLZ-Mg-2 x with x  = 0.05, being 0.291 mS/cm at 293 K and 0.254 eV, respectively.
