在传统的可逆吸放氢材料之中，作为在低于300oC温度下氢的离解压力低于大气压的材料，有钛、铝、铝等金属，但都存在活化困难和吸放氢量小且速度慢等问题。为了排除传统吸放氢材料的缺点并进一步改进性能，寻求不需要进行初期活化处理，氢化反应速度快的高氢化物组成，并且在低 Among the traditional reversible hydrogen absorbing and desorbing materials, titanium, aluminum and aluminum are the dissociation pressures lower than atmospheric pressure at a temperature lower than 300 ° C., but all of them have difficulty in activation and low hydrogen absorption and desorption rate Slow and other issues. In order to eliminate the shortcomings of the conventional hydrogen-absorbing material and further improve the performance, the high hydride composition that does not require initial activation treatment and high hydrogenation reaction rate is sought,
