There are presented a solid-state ion conductor with improved safety and stability including a compound represented by the following chemical formula 1, a method for manufacturing the same, a component for a lithium battery including the same, a negative electrode, a separator for a lithium battery, and a lithium battery. Chemical formula 1 is Li_(3a+b-(c*n))N_aCl_bX_c. In chemical formula 1, X is a negative ion having an average oxidation state of n and is -3 <= n <= -1, and is at least one of Br, I, F, O, S, or P, and 1 <= a <= 4, 1 <= b <= 3, 0 <= c <= 3, and 4.8 <= (a + b + c) <= 5.2. 하기 화학식 1로 표시되는 화합물을 포함하는 고체 이온 전도체, 그 제조방법, 이를 포함하는 리튬전지용 콤포넌트, 음극, 리튬전지용 세퍼레이터, 및 리튬 전지가 제시된다. <화학식 1> Li3a+b-(c*n)NaClbXc 화학식 1 중, X는 평균산화상태(average oxidation state)가 n인 음기온이며, -3≤n≤-1, Br, I, F, O, S, 및 P 중에서 선택된 적어도 하나이며, 1≤a≤4, 1≤b≤3, 0<c≤3, 4.8≤(a+b+c)≤5.2이다.
