Discrete Variational Method

Employing the first principles discrete variational method(DVM), we investigated the electronic structure of LaNi5 hydrogen storage alloys containing various alloying elements, M=Mn,Fe,Co. The results showed that s electrons of H mainly interact with s electrons of hydride-non-forming element Ni, though hydride forming element La have stronger affinity to hydrogen atom. And alloying elements strengthened the bond between B-H, so decreased the capacity of doped-system.

First Principles Calculation

Using the first principles calculation method calculated the Mg substitutional atoms occupying law in LaNi3alloy. The results of total energy showed ,when Mg atoms occupy the bit of 6c,LaNi3alloy is more stable. And substitutional atoms tend to non adjacent. The result of size effect and electronic structure showed that ,the size effect is a major determinant of substitutional Mg substitutional atoms.
