    摘要： 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.

    摘要： A preferred embodiment of the present invention provides a process for making nickel sulfate by converting nickel metal into nickel sulfate, which may be converted to nickel hydroxide. Nickel metal is dissolved in sulfuric acid and oxygen containing gas is introduced to produce a nickel sulfate solution having nickel sulfate and water as illustrated in the following chemical equation. Ni+H2SO4+½O2→NiSO4+H2O The nickel sulfate is filtered and sulfuric acid is continually added to maintain stoichiometry within a reactor until the nickel metal is dissolved. The sulfuric acid, oxygen containing gas and nickel metal may be heated to facilitate the desired reaction. Then, the nickel sulfate may be utilized to produce nickel hydroxide.

    摘要： A process for making a nickel hydroxide material without the necessity of a preamine reactor. The process includes the steps of providing a metal and forming the metal into an active positive electrode material. The process for making a nickel hydroxide material may also include one or more blending steps. The step for forming may include concurrently combining the metal with ammonium ions and hydroxide ions. The step for forming may also include a continuously stirred precipitation reaction of metal ions. In a preferred aspect of the process hereof, the metal may be a secondary nickel source, such as a spent or virgin electrolyte solution from a nickel electrorefining process, nickel electroless plating process or nickel electroplating process.
