Abstract
A solid electrolyte ceramic material that includes sintered solid electrolyte particles containing, at least, lithium (Li), lanthanum (La), bismuth (Bi), and oxygen (O), wherein the Bi is at a higher concentration in a vicinity of a grain boundary of the sintered solid electrolyte particles than in a grain interior of the sintered solid electrolyte particles.
Claims19
A solid electrolyte ceramic material comprising:
- sintered solid electrolyte particles containing, at least, lithium (Li), lanthanum (La), bismuth (Bi), and oxygen (O),
- wherein the solid electrolyte ceramic material has a garnet-type crystal structure in which Bi is present as a solid solution in the garnet-type crystal structure, and wherein a Bi amount x1 in a vicinity of grain boundaries is greater than a Bi amount x2 in a grain interior.
