Abstract

Abstract

Mischmetal ML (La-rich) was used to study MLNi_3.85-xMn_0.4Co_0.75Al_x(x=0.1~0.5) hydrogen storage alloys. Their activation processes and hydrogen absorption-desorption performances were investigated. The results show that the increase of aluminum content in the alloy can lower the plateau pressure and decrease the amount of hydrogen absorbed. It seems that MLNi_3.85-xMn_0.4Co_0.75Al_x(x=0.1~0.3) alloys are prospective.
