Abstract: A method for preparing magnesium-based hydrogen storage materials is provided to improve the hydrogen storage rate of magnesium hydroxide while minimizing the reduction of hydrogen storage capacity of the magnesium hydroxide, by using high-energy ball milling. A mixture of magnesium hydroxide and transition metal halide is formed(S10). The mixture and balls are inputted into a case(S20). Inert gas or hydrogen gas fills the case(S30). A high-energy ball milling process is performed on the mixture for 5-30 minutes(S40). In the step of forming the mixture, 0.1-5 mol% of transition metal halide powder is added based on the mixture. The balls have diameters of 5-30 mm. A weight ratio of the mixture to the balls is 1:1-1:100.

Abstract: 수소 저장 물질 및 그 제조 방법에서, 수소 저장 물질은 리튬붕소수소화물과 세륨계 물질의 혼합체를 포함한다. 따라서, 리튬붕소수소화물 및 세륨계 물질을 혼합함으로 두 물질 간의 화학반응을 통해 순수한 리튬붕소수소화물과 비교하여 낮은 온도에서 탈수소화반응을 일으킬 수 있다. 또한, 탈수소생성물의 수소화반응이 상대적으로 용이하여 탈수소화/수소화 반응의 가역성을 높일 수 있다.

Abstract: PURPOSE: A hydrogen storage material and a manufacturing method thereof are provided to facilitate a hydrogenation of a dehydrogenated product in a lower temperature, and to improve reversibility of the dehydrogenation and the hydrogenation. CONSTITUTION: A hydrogen storage material includes lithium borohydride and a cerium-based material. The cerium-based material can form cerium hydride by reacting with the cerium hydride, metal cerium and the lithium borohydride. The molar ratio of the cerium hydride for the lithium borohydride is 3:1~10:1. The manufacturing method of the hydrogen storage material comprises the following steps: forming mixed powder including the lithium borohydride and the cerium-based material(S100); and ball-milling the mixed powder(S200).
