- We prepared and optimized the ionically conducting perovskite-type Li0.33La0.56TiO3 by an adipic acid-assisted sol-gel process. A high ionic conductivity of 0.131 mS cm?닋1 was obtained at an ambient temperature by adjusting the synthesis temperature, holding time, and cooling process. A dramatic improvement in the Li0.33La0.56TiO3 conductivity was noted in each step. Interestingly, a tetragonal-to-cubic structural transition was evident during the quenching process unlike in the conventional slow cooling process. An increase in the bottleneck site volume was observed that facilitated Li+ ion migration for enhanced conductivity.
