摘要： A modified A2B7 type hydrogen storage alloy having reduced hysteresis. The alloy consists of a base AXBy hydrogen storage alloy, where A includes at least one rare earth element and also includes magnesium, B includes at least nickel, and the atomic ratio of x to y is between 1:2 and 1:5. The base alloy is modified by the addition of at least one modifier element which has an atomic volume less than about 8 cm3/mole, and is added to the base alloy in an amount sufficient to reduce the absorption/desorption hysteresis of the alloy by at least 10% when compared with the base alloy.
