Lithium ion conductive garnet-type oxide
The purpose of the present invention is to provide an oxide-based solid electrolyte having high lithium ion conductivity. The present invention is a lithium ion conductive garnet-type oxide containing Li, La, Ga, Zr, a halogen element, and oxygen, and having a lithium ion conductivity at room temperature of 1.0 * 10 <-3 > S/cm or more. The ratio of Ga to 1 mol of the oxide is preferably 0.5 mol or less. In addition, the halogen element is at least one element selected from the group consisting of Cl, Br, and I, and the ratio of Li to 1 mol of the oxide is preferably 6.1 mol or more and less than 6.5 mol.
本发明的目的在于，提供锂离子传导率高的氧化物系固体电解质。本发明是一种锂离子传导性石榴石型氧化物，其包含Li、La、Ga、Zr、卤族元素和氧，所述锂离子传导性石榴石型氧化物在室温下的锂离子传导率为1.0×10‑3S/cm以上。Ga相对于前述氧化物1摩尔的比例优选为0.5摩尔以下。另外，前述卤族元素为选自由Cl、Br和I组成的组中的至少1种，Li相对于前述氧化物1摩尔的比例也优选为6.1摩尔以上且小于6.5摩尔。
