    摘要： An electrochemical hydrogen storage alloy having decreased hydrogen overpressure as well as other desirable operational parameters, comprising on an atomic percent basis: 14 to 22 percent vanadium; 28 to 39 percent nickel; 7 to 15 percent titanium; 15 to 34 percent zirconium; and at least one member selected from the group consisting of 0.001 to 7 percent chromium, 0.001 to 7 percent cobalt, 0.001 to 7 percent iron, 0.001 to 3.6 percent manganese, and 0.001 to 2.7 percent aluminum, wherein the atomic ratio of the vanadium to zirconium is in the range of 1:2.26 to 1:0.68. An electrochemical hydrogen storage alloy having a reduced self-discharge rate comprising an alloy having a heterogeneous, disordered microstructure resulting from changes in the mutual solubility of the elements of the alloy, wherein hydrogen in a particular phase is not easily discharged either though low surface area, or an oxide of limited porosity or catalytic property.
