Li-ion conductive oxide ceramic material including garnet-type or similar crystal structure

摘要

A Li-ion conductive oxide ceramic material including a garnet-type or similar crystal structure according to an aspect of the present disclosure contains Li, La, Zr, and O, the material further containing one or more elements selected from the group consisting of rare-earth elements. A Li-ion conductive oxide ceramic material including a garnet-type or similar crystal structure according to the other aspects of the present disclosure is represented by the following composition formula (1) Li_7+xLa₃Zr_2−xA_xO₁₂ where A is one or more elements selected from the group consisting of rare-earth elements, and x is a number such that 0x≤0.5.
