The results show that although both Ni substitution and Mg vacancies are effective in desorbing hydrogen at lower temperatures, the substitution of Ni at the Mg site is energetically more favorable than the formation of Mg vacancies. The Ni atoms of NiF2 can replace some Mg atoms of MgH2 systems, the reaction of NiF2+3MgH2=MgF2+Mg2NiH4 during mill process is accelerated, thus, MgH2 with the higher stability can be changed into Mg2NiH4. Because of a ternary hydride Mg2NiH4 with lower stability forming, the dehydrogenating properties on Ni doped MgH2 systems are improved.

结果表明：Ni替代Mg和创造Mg空位对MgH2体系解氢而言，均发挥有益作用，而形成Mg空位所需能量(6.51 eV)高于Ni替代Mg所需能量(2.12 eV)，表明低温下Ni替代Mg对MgH2体系解氢而言更有利，至此NiF2中的Ni替代MgH2中的Mg，有利于加速化学反应NiF2+3MgH2=MgF2+Mg2NiH4向右进行，使结构稳定的MgH2发生转变，生成结构不稳定的Mg2NiH4，这样体系解氢过程不是通过MgH2，而是转变为通过Mg2NiH4进行，因此，Ni掺杂提高了MgH2体系的解氢性能。
