Lithium ion conductive solid electrolyte, method for producing the same, solid electrolyte for lithium secondary battery using the solid electrolyte, and all solid lithium battery using the solid electrolyte for secondary battery

摘要

Disclosed is a lithium ion-conductive solid electrolyte exhibiting high lithium ion conductivity even at room temperature which is hardly oxidized and free from problems of toxicity and contains as components lithium (Li) element, boron (B) element, sulfur (S) element, and oxygen (O) element, and the ratio between sulfur element and oxygen element (O/S) is 0.01 to 1.43.
