SOLID ELECTROLYTE MATERIAL, SOLID ELECTROLYTE, AND CELL

摘要

This embodiment provides a solid electrolyte material. The solid electrolyte material is an oxide indicated by ABO3. The A site of the oxide includes Li and a hole. The cubic root (V1/3) of the unit lattice volume is in the range 386 pm @ V1/3 @ 397 pm. The top (nutop) of the absorption peak in the infrared absorption spectrum fulfills formula (1). nutop(cm-1) = 4.7 × V1/3 (pm) - b (formula (1)); however 1220 @ b @ 1240.
