The structure and electrochemical properties of nanocrystalline Mg2Ni and Mg2Ni/Pd nanocomposite have been studied. The materials were prepared by mechanical alloying. In nanocrystalline Mg2Ni powder, discharge capacities up to 100 mAźhźg-1 were measured. It was found that mechanically coated Mgbased alloys with palladium have effectively reduced the degradation rate of the studied electrode materials. Finally, the properties of nanocrystalline alloys and their nanocomposites were compared to those of microcrystalline samples. The electronic structure was studied by ab initio calculations, which showed that the 3b positions in the unit cell are preferred by the Pd impurities.
