摘要:
The LaNi5 alloy is a typical
hydrogen-storage material. On the basis of the empirical electron theory of solids and
molecules(EET), the valence electron structures of the LaNi5 alloy and bond
energies of main bonds between upper strata and lower strata for substitution of Co andor
Mn for partial Ni in the LaNi5 alloy are calculated. The results indicate that
these bond energies increase when Mn is subslituted for Ni2, or Co is
substituted for Ni1 or Ni2. When both Mn and Ni are substituted for
Ni, the bond energies increase greatly. as a result of which the lifetime of the LaNi5
alloy increases.
