Material for solid electrolyte

摘要

A material capable of producing a sintered body of cubic system garnet type Li7La3Zr2O12 as a solid electrolyte having specified ion conductivity by firing at relatively low temperature in short time. The material for the solid electrolyte is an oxide containing Li, La, Zr and Bi, and the oxide has a cubic system garnet crystal structure where La sites are partly or entirely substituted by Bi.
