In order to demonstrate the importance of local structural study for the lithium ionic conductor, an investigation was made of the local structure of the Li+ conductor with perovskite structure, LiyLa(1–y)/3NbO3 (y = 0 to 0.25) using the extended X-ray absorption fine structure technique. The results of these measurements imply that changes of the local structure were more crucial for the property on ionic conductivity than that of the lattice parameter obtained by X-ray diffraction technique.
