Bulk single crystals of the perovskite LixLa(1-x)/3NbO3, which is one of the materials used as the solid electrolyte in all-solid lithium-ion batteries, have been grown for the first time by the directional solidification method. The ionic conductivity measured in the growth direction of the single crystal wafer of LixLa(1-x)/3NbO3 and the anisotropy of ionic conduction in solid electrolyte were experimentally confirmed for the first time by using LixLa(1-x)/3NbO3 single crystals. Here, the results of four experiments on LixLa(1-x)/3NbO3 bulk single crystals are presented:  (1) growth of solid electrolyte LixLa(1-x)/3NbO3 bulk single crystals, (2) ionic conduction in LixLa(1-x)/3NbO3 single crystal, (3) anisotropy of ionic conduction in LixLa(1-x)/3NbO3 single crystal and (4) microstructure analysis of LixLa(1-x)/3NbO3 single crystal.
