Abstract
Lithium (Li) ion conductivities of Nd-doped (Li, La)TiO3 (LLNT) ceramics are evaluated as a function of Nd-loading. The bulk ion conductivity, σdc, improves for the specimen with ∼ 0.75 mol% Nd. The conductivity of the 0.5 mol% Nd-loaded LLNT is σdc = 1.26 × 10- 3 S cm- 1 at room temperature. It is the highest conductivity measured, and is 1.33 times higher than that of the non-doped ceramic. The enhancement of the Li ion conductivity with Nd-doping in the LLNTs is attributed to an increase in the volume fraction of the A-site disordered cubic phase.
