Title (EN) NICKEL-HYDROGEN BATTERY AND PRODUCTION METHOD THEREOF
(FR) BATTERIE DE NICKEL HYDROGÈNE ET SON PROCÉDÉ DE FABRICATION
(JA) ニッケル水素電池およびその製造方法
Abstract:
(EN) An enclosed type nickel-hydrogen battery provided with high output characteristics with excellent charge/discharge cycle characteristics retained, and a production method thereof. A hydrogen storing electrode as an electrode is used that uses hydrogen storing alloy powder consisting of a rear-earth element and a metal element including Ni and excluding rear-earth element, and having a specific equilibrium hydrogen dissociation pressure, a specific mass saturation magnetization, and a specific ratio between a rear-earth element and a non-rear-earth element. The hydrogen storing electrode is used, and at least one welding point out of a welding point between the inner surface of a sealing plate and a collector lead and a welding point between the collector lead and an upper collector plate is welded by energizing between an anode terminal and a cathode terminal after sealing by means of an external power supply to produce an enclosed type nickel-hydrogen battery.
(FR) La présente invention concerne une batterie de nickel hydrogène de type fermé dotée de caractéristiques de sortie élevées avec d'excellentes caractéristiques de cycles de charge/de décharge conservées, ainsi que son procédé de fabrication. Une électrode de stockage d'hydrogène formant électrode est employée, qui utilise une poudre d'alliage de stockage d'hydrogène consistant en un élément du groupe des terres rares et en un élément métallique comprenant Ni et excluant l'élément du groupe des terres rares, présentant une pression de dissociation de l'hydrogène à l'équilibre spécifique, une aimantation par saturation massique spécifique et un rapport spécifique entre un élément du groupe des terres rares et un élément n’étant pas du groupe des terres rares. L'électrode de stockage de l'hydrogène est utilisée et au moins un point de soudure parmi un point de soudure entre la surface interne d’une plaque d’étanchéité et un fil de collecteur, et un point de soudure entre le fil de collecteur et une plaque de collecteur supérieure, est soudé par excitation entre une borne d'anode et une borne de cathode après étanchéification au moyen d'une alimentation en énergie externe afin de produire une batterie nickel hydrogène de type fermé.
(JA) 優れた充放電サイクル特性を維持しつつ高出力特性を備えた密閉形ニッケル水素電池およびその製造方法を提供することを課題とする。 水素吸蔵電極を、希土類元素とNiを含む希土類以外の金属元素からなる水素吸蔵合金粉末であって、特定の平衡水素解離圧、特定の質量飽和磁化および希土類元素と非希土類金属元素の比が特定の比を有する水素吸蔵合金粉末を適用した電極とすることによって前記課題を解決する。また、該水素吸蔵電極を適用し、封口板の内面と集電リードの溶接点および集電リードと上部集電板の溶接点のうち少なくとも一方の溶接点を、封口後の電池の正極端子と負極端子間に外部電源により通電することにより溶接して密閉形ニッケル水素電池とする。
