摘 要: 对苯溶液中球磨的La2Mg16Ni合金的储氢性能进行了研究。 XRD和SEM分析表明: 球磨后合金颗粒粒径减小, 且有明显的非晶化趋势;由合金和有机苯溶剂在球磨过程中形成的EDA (electron donor-acceptor) 体系极大地提高了合金的活化性能;球磨后的合金即使在低温下也具有良好的吸氢速率; 延长球磨时间, 可改善合金的吸氢性能。

Abstract:The La2Mg16Ni hydrogen storage alloy was modified by ball milling in benzene. XRD and SEM analysis indicate that the modified alloy is amorphized to some extent besides of the reduction of particle size. The use of benzene is very important in improving the activation properties by the EDA (electron donor-acceptor) complexes formation. These as-milled alloys have relatively fast absorption kinetics even at low temperature. With the milling time increased, the hydriding properties are improved.
