Full TextAbstract
Li-Ion and Ni-MH batteries are the best candidates for Electric Vehicles. Despite higher energy densities of Li-Ion batteries, because of economical reason Ni-MH batteries are still attractive for scientist. In this study, the intermetallic compound La2Mg0.9Y0.1Ni10Mn0.5 based on LaNi5 structures, which is a suitable absorbent for hydrogen storage in the solid phase, was produced by vacuum arc melting (VAR). The hydrogen properties of this alloy have been measured using the Sievert volumetric method. Based on the results, absorption and desorption of hydrogen with high kinetics (less than 5 minutes) and with a maximum hydrogen storage of 1.8 wt% at room temperature for La2Mg0.9Y0.1Ni10Mn0.5 alloy were obtained. Electrochemical analysis shown that the energy density which the alloy can reversibly deliver is about 300 mAh/g
