固体電解質Li_xLa_(1-x)/3NbO₃のバルク単結晶

抄録

  Bulk single crystals of the perovskite Li_xLa_(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 Li_xLa_(1-x)/3NbO₃ and the anisotropy of ionic conduction in solid electrolyte were experimentally confirmed for the first time by using Li_xLa_(1-x)/3NbO₃ single crystals. Here, the results of four experiments on Li_xLa_(1-x)/3NbO₃ bulk single crystals are presented:

  (1) growth of solid electrolyte Li_xLa_(1-x)/3NbO₃ bulk single crystals, (2) ionic conduction in Li_xLa_(1-x)/3NbO₃ single crystal, (3) anisotropy of ionic conduction in Li_xLa_(1-x)/3NbO₃ single crystal and (4) microstructure analysis of Li_xLa_(1-x)/3NbO₃ single crystal.
