  • Patent number: 11081726
    Abstract: A solid state electrolyte having a garnet type crystal structure is provided. The chemical composition of the solid state electrolyte includes lithium, lanthanum, zirconium, oxygen, and sulfur. The content of sulfur in the solid state electrolyte is between 5 mol % and 35 mol % based on the content of oxygen in the solid state electrolyte. A solid state battery including a positive electrode layer, a negative electrode layer, and a solid state electrolyte layer is also provided. The solid state electrolyte layer is disposed between the positive electrode layer and the negative electrode layer. The solid state electrolyte layer includes the solid state electrolyte.
