摘要： A method for manufacturing hydrogen storage alloy particles comprises steps of obtaining a melt of the hydrogen storage alloy and pulverizing the hydrogen storage alloy by water atomizing process, whereby the melt is pulverized by contacting or colliding with high-speed jetting thereto to be dispersed in the form of solidified fine particles. By employing an aqueous solution of hypophosphorous acid or an alkali aqueous solution in place of water during the water atomizing process, or by etching the oxide films once formed on the surface of the hydrogen storage alloy particles with an aqueous solution of a strong acid, the thickness of the oxide film can be made thinner, and thus a high discharge capacity of a battery configured with a negative electrode comprising the alloy particles can be realized.

摘要： The invention provides long life alkaline storage batteries free from short-circuiting using plates having a punching metal as a substrate. In the alkaline storage batteries of the present invention, at least one of the positive plate and the negative plate comprises a punching metal as a substrate, the size thereof is different from that of another plate, and the plates are arranged so that the cut side of the plate having the punching metal substrate at which the substrate is cut through the punched portions does not overlap the side of the adjacent plate of opposite polarity. The plates having such a construction prevents needle-shaped projections produced by cutting the substrate through the punched portions from causing the short-circuiting with the adjacent plate of opposite polarity.
