摘 要: 對(duì)苯溶液中球磨的La2Mg16Ni合金的儲(chǔ)氫性能進(jìn)行了研究。 XRD和SEM分析表明： 球磨后合金顆粒粒徑減小， 且有明顯的非晶化趨勢(shì)；由合金和有機(jī)苯溶劑在球磨過(guò)程中形成的EDA (electron donor-acceptor) 體系極大地提高了合金的活化性能；球磨后的合金即使在低溫下也具有良好的吸氫速率； 延長(zhǎng)球磨時(shí)間， 可改善合金的吸氫性能。

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.
