| Abstract: | To Search the affection of a new way doping on AB5-type hydrogen storage alloys,La0.7Ni2.65Co0.75Mn0.1(AB5 type) hydrogen storage alloys,melting-dopped with TiMn1.5 alloy(4%,8%),have been investigated to illustrate the effects of doping on its structure and properties.XRD analysis indicated that the dopped alloy samples consist of a main LaNi5phase and small(NiCo)3Ti phase,the formation of(NiCo)3Ti phase will result in the decrease of hydrogenation and high-rate dischargeabilities.Further analysis of electr... |
