Zusammenfassung:	The present invention relates to solid electrolyte, methods for preparing same, and a lithium secondary battery comprising same. The sulfide-based solid electrolyte according to the present invention is represented by chemical formula 1. [Chemical formula 1] Li6(1-y)A2yP1-yS5-2yX1-y In chemical formula 1, A is an element in the boron group , X is halogen, and 0 < y ≤ 1. La présente invention concerne un électrolyte solide, des procédés de préparation de celui-ci, et une batterie secondaire au lithium le comprenant. L'électrolyte solide à base de sulfure selon la présente invention est représenté par la formule chimique 1. [Formule chimique 1] Li6(1-y)A2yP1-yS5-2yX1-y Dans la formule chimique 1, A est un élément dans le groupe bore, X est halogène, et 0 < y ≤ 1. 본 발명은 고체전해질, 이의 제조방법 및 이를 포함하는 리튬이차전지에 관한 것이다. 본 발명에 따른 황화물계 고체전해질은 하기 화학식 1로 표현된다. [화학식 1] Li6(1-y)A2yP1-yS5-2yX1-y 상기 화학식 1에서 A는 붕소족 원소이고, X는 할로겐 원소이며, 0 < y ≤ 1 이다.
