LITHIUM ION CONDUCTIVE SOLID ELECTROLYTE

摘要

PROBLEM TO BE SOLVED: To provide an lithium ion conductive solid electrolyte having high ion conductivity, allowing a highly ion conductive solid electrolyte layer to be produced without using a high-temperature sintering process. SOLUTION: The lithium ion conductive solid electrolyte comprises phosphate containing lithium and titanium and a lithium ion conductive amorphous solid electrolyte, mixed without sintering. The lithium ion conductive amorphous solid electrolyte is, preferably, a material containing sulfide as a main component.
