    Abstract: A hydrogen storage alloy having an atomically engineered microstructure that both physically and chemically absorbs hydrogen. The atomically engineered microstructure has a predominant volume of a first microstructure which provides for chemically absorbed hydrogen and a volume of a second microstructure which provides for physically absorbed hydrogen. The volume of the second microstructure may be at least 5 volume % of atomically engineered microstructure. The atomically engineered microstructure may include porous micro-tubes in which the porosity of the micro-tubes physically absorbs hydrogen. The micro-tubes may be at least 5 volume % of the atomically engineered microstructure. The micro-tubes may provide proton conduction channels within the bulk of the hydrogen storage alloy and the proton conduction channels may be at least 5 volume % of the atomically engineered microstructure.

    Abstract: The present invention relates to rechargeable nickel metal hydride batteries and methods for making the same. More particularly, the present invention relates to rechargeable nickel metal hydride batteries having a precharge in the negative electrode sufficient for oxidation prevention in the negative electrode. The present invention discloses a nickel metal hydride battery, wherein the precharge of the negative electrode may be supplied by a variety of sources. The positive active material of the positive electrode may have positive active particles, such as nickel hydroxide, having a precursor coating that incorporates cobalt material capable of forming a conductive network. Sources other than cobalt-containing materials in the positive electrode include hydrogen gas provided directly to the negative active material, nickel aluminum mixed with the negative active material, the etching of the negative active material with an alkaline solution and borohydride chemically charging the negative active material. Preferably, a majority of the precharge of the negative electrode is supplied by sources other than cobalt-containing materials in the positive electrode.

    Abstract: 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.
