摘要： The invention relates to a new method of manufacturing a sealed rechargeable alkaline battery including metal oxides as positive electrode active materials and a hydrogen absorbing alloy as a negative electrode material. The basic principle of the method is that, instead of the conventional electrochemical formation, the property of a hydrogen absorbing alloy is utilized to cause the negative electrode to absorb hydrogen to thereby achieve precharged portions within the negative electrode having a relatively larger capacity as compared with the positive electrode. Regardless of the kind of positive electrode, the method of the invention insures a broad freedom in the capacity appropriation between the positive and negative electrodes.

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.
