Temat: Contribution to the study of ternary metal compounds based on La-Ni-Mg, intended for electrochemical applications
Streszczenie: The objective of our work is a contribution to the study of ternary compounds at the base of La-Ni-Mg, such as the compounds La1.5Mg1.5Ni9 and La1.5Mg0.5Ni7 belong to the family AB3 and A2B7, respectively. All these compounds are produced by mechanical grinding at different grinding times and mass ratio of beads / powder 8: 1. The structural characterization is carried out by DRX in order to identify the different existing phases. The electrochemical characterization is carried out through two methods of galvanic-static and potential-dynamic polarization in order to test the performance of these two compounds as active material for the anode of Ni-MH batteries
