【摘要】 首先分别简述了气体雾化法、熔体快淬法和铸带法制备储氢合金的微观组织结构特征和电化学性能。其次从合金电极充-放电机理出发分析了具有易活化、高容量、长寿命及高倍率性能等优异电化学性能的储氢合金应该具有的理想徽观组织特征。说明了气体雾化法和快淬法在储氢合金制备中固有的弊端,指出铸带法是3种特种工艺方法中制备高性能AB5型储氢合金的最佳选择。更多还原

【Abstract】 Firstly, the microstructure and the electrochemical properties of hydrogen storage alloys prepared, respectively, by gas atomization, melt quenching and strip casting were presented. Secondly, the microstructure of hydrogen storage alloys having electrochemical excellent properties, such as easy activation, high capacity, long life and high rate property, was analyzed according to the mechanism of alloy elec-trode’ s charge-discharge process. Then, the intrinsic disadvantages of hydrogen storage alloys prepared by gas atomization and melt quenching were illuminated and showing that the strip casting is the best technics in preparing AB5 hydrogen storage alloys in these three methods. The investigating emphases of hydrogen storage alloys prepared by strip casting are advised simultaneously .更多还原
