| 中文摘要 | Sn-substituted, LaNi5-based rapidly solidified alloys with low Co content, La(1-x)A(x)Ni(4.25)Co(0.5)Sn(0.25)(A=La, Nd, Ce,and x=0.2),were prepared by melt-spinning. The microstructure of the as-spun alloys was observed with SERI and the element distribution of the as-spun and annealed alloys was analyzed by EDX. It is found that the as-spun alloys had fine grains. However, there was Sn segregation in the grain boundaries of the as-spun alloys. XRD patterns show that for the as-spun alloys the lattice strain could be alleviated through vacuum annealing. The electrochemical performance of the as-spun and heat-treated alloys was investigated. It is found that the Ce-containing as-spun alloy had a cycle Life more than 300 cycles. After heat-treatment, the electrochemical performance of the Ce-free alloys could be further improved, which is attributed to the alleviation of the lattice strain and the change of Sn distribution.
