Abstract
[OBJECTS] An object of the present invention is to provide a lithium-ion-conductive ceramic material having a target ion conductivity, while suppressing production cost. Another object is to provide a high-performance lithium battery, while suppressing production cost, by virtue of having the lithium-ion-conductive ceramic material. The lithium-ion-conductive ceramic material contains Li, La, and Zr, as well as at least one of Mg and A (wherein A represents at least one element selected from the group consisting of Ca, Sr, and Ba) and which has a garnet-type crystal structure, wherein the elements contained in the ceramic material satisfy the following mole ratio conditions (1) to (3): (1) 1.33≤Li/(La+A)≤3; (2) 0<Mg/(La+A)≤0.5; and (3) 0<A/(La+A)≤0.67, and a lithium battery employing the ceramic material.
