Document Type and Number:
Japanese Patent JP6672848
Kind Code:
B2
Abstract:
The invention provides a Li-ion conductive oxide ceramic material with a garnet type crystal structure or a crystal structure similar to a garnet type, and internal resistance component in a crystalline grain has high contribution on ionic conductance. The Li-ion conductive oxide ceramic material with a garnet type crystal structure or a crystal structure similar to a garnet type contains Li, La, Zr, and O, and also contains more than one element selected from rare earth elements.
