ABSTRACT:
A method for providing a multicomponent alloy for hydrogen storage and for a hydride electrode. The steps involved in the method include: providing a quantity of elements A, B, C, . . . , where said elements are selected from the group consisting of Mg, Ti, V, Cr, Mn, Fe, Co, Ni, Al, Y, Zr, Nb, Pd, Mo, Ca, Si, C, Cu, Ta, and rare earth elements, the quantity of the elements including nickel and at least two other elements from said group; apportioning the quantity of the elements in order to form a composition A.sub.a B.sub.b C.sub.c . . . such that the composition A.sub.a B.sub.b C.sub.c . . . contains 5 to 65 mole percent of nickel and further such that the composition A.sub.a B.sub.b C.sub.c . . . has, when in the form of a multicomponent alloy, a heat of hydride formation that is in a range of between -3.5 and -9.0 kcal/mold H; and, finally, melting the composition A.sub.a B.sub.b C.sub.c . . . in order to form the desired multicomponent alloy.
