Beschreibung
Zusammenfassung:	The present invention relates to a lithium ion conductive sulfide-based solid electrolyte comprising lithium (Li), sulfur (S), phosphorous (P), indium (In), and selenium (Se) and having a crystal structure of InSe. The present invention provides lithium ion conductive sulfide-based solid electrolyte comprising indium selenide which enables a solid-state cell having excellent charging and discharging performance, high energy efficiency, and a long service life to be manufactured and a method for manufacturing the same. A lithium ion conductive sulfide-based solid electrolyte comprises Li, S, P, In, and Se and is represented by chemical formula 1. In chemical formula 1, a is 0.5-0.8, b is 0.1-0.4, c is 0.01-0.3 and a + b + c equals 1. 본 발명은 리튬 원소(Li), 황 원소(S), 인 원소(P), 인듐 원소(In) 및 셀레늄 원소(Se)를 포함하고, InSe의 결정 구조를 갖는 리튬 이온 전도성 황화물계 고체전해질 및 이의 제조방법에 관한 것이다.
