Abstract

본 발명은 Ti-Mn계 수소저장합금에 관한 것이다. 좀 더 구체적으로, 본 발명은 높은 수소저장용량과 평탄한 수소방출 평형압력을 나타내며 차아화학양론적(hypostoichiometric) 조정과 C14 결정구조를 지는 Ti-Mn계 수소저장합금에 관한 것이다. 본 발명의 수소저장합금은 C14 결정구조를 지니며, 하기 일반식으로 표시된다:
TiuZrvMnwCrxVyXz
상기 식에서, X는 Fe, AL 및 Ni로 구성되는 그룹으로부터 선택된 1종 이상의 원소를 나타내며 : u, v, w, x, y 및 z은 각 성부의 몰수이고 ; 0.7＜u＜1.0; 0＜v＜0.3; 1.0 w 1.3; 0.1 x 0.4; 0＜y＜0.3; 0 z 0.2; 0.7＜u+v＜1.0; 1.4 w+x 1.7; 및, 1.3≤w+x+y+z＜2.0이다. 본 발명의 차아화학양론적 조성 및 C14결정구조를 지닌 Ti-Mn계 수소저장합금은 종래의 Ti-Mn계 합금에 비하여 수소저장용량이 크며, 적절하고 넓은 영역의 평형압력을 지니고 있다는 것을 확인하였다.

Description
