淬速的增加先增加后降低,导致这一不同变化趋势的主要原因是合金的气态及电化学贮氢动力学具有不同的控制因素. 参考文献: [1] Jain I P, Lal C, Jain A. Hydrogen storage in Mg: A most promising material[J]. International Journal of Hydrogen Energy, 2010, 35(10... content to x=0.4. Both the melt spinning and the La substitution visibly ameliorate the gaseous and electrochemical hydrogen storage kinetics of the alloys. The substitution of La for Mg causes......
Study on High Rate Discharge Performance and Mechanism of AB5 Type Hydrogen Storage Alloys 于军1,郭靖洪2,杨柯2,刘国忠1,陈德敏2,张建海1 (1.Suppo Battery Co.,Ltd.,Shenyang 110015,China;2.Institute of Metal Research... of hydrogen storage alloys were investigated. It is found that the activity, discharge capacity and high rate dischargeability of the alloys are improved after physical and chemical modification......
