| 简介 |
An object of the present invention is to provide a sealed nickel metal-hydride that shows an excellent output power performance, while maintaining an excellent charge/discharge cycle performance, and a method of manufacturing the same. A hydrogen absorbing electrode is made of hydrogen absorbing alloy powder containing rare earth elements and Ni and other metal elements other than rare earth elements and the hydrogen absorbing alloy powder shows a specific saturation mass susceptibility and a specific content ratio of the rare earth elements to the non-rare earth elements. A nickel metal-hydride battery is formed by using such a hydrogen absorbing electrode and welding at least the welded points of the inner surface of a sealing plate and a current collecting lead or the welded points of the current collecting lead and an upper current collecting plate by causing an electric current to flow between the positive electrode terminal and the negative electrode terminal of the battery from an external power source after sealing the battery. |
