HIGH CONDUCTING OXIDE - SULFIDE COMPOSITE LITHIUM SUPERIONIC CONDUCTOR

摘要

A solid electrolyte for a lithium-sulfur battery includes particles of a lithium ion conducting oxide composition embedded within a lithium ion conducting sulfide composition. The lithium ion conducting oxide composition can be Li₇La₃Zr₂O₁₂ (LLZO). The lithium ion conducting sulfide composition can be β-Li₃PS₄ (LPS). A lithium ion battery and a method of making a solid electrolyte for a lithium ion battery are also disclosed.
