Effects of substitution with foreign metals on the crystallographic, thermodynamic and electrochemical properties of AB,-type hydrogen storage alloys were investigated. The unit cell volume of MmNi,\_xAl, (Mm = mischmetal, 0.2 < x < 1.0) alloys and the values of enthalpy change (-AH) in hydride form
Effect of stoichiometric ratio on the electrochemical properties of negative electrodes was investigated for alloys with composition Mm(Ni,,,Mno.4Al,,,Co~,,), (Mm = misch metal, 0.88 < x < 1.12). The discharge capacity at a current density of 0.2Ag-' increased with an increase in unit cell volume of
