Hydride-forming alloy comprises a metallic crystalline phase. Hydride-forming alloy comprises a crystalline phase of A 5B 19type of formula R(1-y)Mg(y)Ni(3.8+-0.1-z)M(z). R = La, Ce, Nd or Pr; M = Al, Co, Mn, Fe, Cu, Zr, Sn or Cr, preferably Co(a)Al(b); a, b = less than 0.15; y = 0-0.3, preferably greater than 0.15; and z = = 0.5, preferably = 0.3. Independent claims are included for: (a) a negative electrode comprising a material obtained from the alloy; (b) an alkaline-nickel metal hydride battery comprising the electrode; and (c) a process of preparing the alloy comprising fusion of the simple elements of alloy and (hyper)hardening of the alloy. |
