Abstract

We synthesized perovskite-type Li ion conductor, (La2/3–1/3p Lip)(Mg1/2W1/2)O3 (p =0.05, 0.11 and 0.14), and investigated the variation of the Li ion conductivity with p. Furthermore, the variation of the activation energy with the valence of B-site ion was elucidated from the site potential at A-site and a bottleneck position. As results, it is suggested that the Coulomb repulsion between B-site and Li ions at the bottleneck dominates the activation energy for (La2/3–1/3p Lip)(Mg1/2W1/2)O3.
