Title (EN) NICKEL-METAL HYDRIDE STORAGE BATTERY
(FR) BATTERIE RECHARGEABLE HYBRIDE NICKEL-MÉTAL
(JA) ニッケル水素蓄電池
Abstract:
(EN) This nickel-metal hydride storage battery is provided with: a battery case having an opening; an electrode group and an alkaline electrolyte solution, which are contained within the battery case; a sealing body for sealing the opening; and a gasket which is interposed between the battery case and the sealing body. The electrode group comprises: a positive electrode containing a positive electrode active material; a negative electrode containing a negative electrode active material; and a separator that is interposed between the positive electrode and the negative electrode. The positive electrode active material contains a nickel compound; and the negative electrode active material contains a hydrogen storage alloy that is capable of electrochemically storing and releasing hydrogen. The hydrogen storage alloy has an AB5-type crystal structure, and contains an element L that is likely to be positioned in the A site and an element M that is likely to be positioned in the B site. The element L includes at least Zr. The alkaline electrolyte solution contains NaOH at a concentration of 4.6 mol/L or more.
(FR) La présente invention concerne une batterie rechargeable hybride nickel-métal qui est pourvue : d'un boîtier de batterie ayant une ouverture; d'un groupe d'électrodes et d'une solution électrolytique alcaline, qui sont contenus dans le boîtier de batterie; d'un corps d'étanchéité destiné à fermer de façon étanche l'ouverture; et d'un joint qui est intercalé entre le boîtier de batterie et le corps d'étanchéité. Le groupe d'électrodes comprend : une électrode positive contenant un matériau actif d'électrode positive; une électrode négative contenant un matériau actif d'électrode négative; et un séparateur qui est intercalé entre l'électrode positive et l'électrode négative. Le matériau actif d'électrode positive contient un composé à base de nickel; et le matériau actif d'électrode négative contient un alliage de stockage d'hydrogène qui peut stocker et libérer de l'hydrogène de manière électrochimique. L'alliage de stockage d'hydrogène présente une structure cristalline de type AB5 et contient un élément L qui est susceptible d'être positionné dans le site A, et un élément M qui est susceptible d'être positionné dans le site B. L'élément L comprend au moins du zirconium (Zr). La solution électrolytique alcaline contient de l'hydroxyde de sodium (NaOH) à une concentration égale ou supérieure à 4,6 mol/l.
(JA) ニッケル水素蓄電池は、開口部を有する電池ケースと、電池ケース内に収容された電極群およびアルカリ電解液と、開口部を封口する封口体と、電池ケースおよび封口体の間に介在するガスケットと、を備える。電極群は、正極活物質を含む正極と、負極活物質を含む負極と、正極および負極の間に介在するセパレータと、を備える。正極活物質は、ニッケル化合物を含み、負極活物質は、水素を電気化学的に吸蔵および放出可能な水素吸蔵合金を含む。水素吸蔵合金は、AB5型の結晶構造を有し、かつAサイトに位置し易い元素LおよびBサイトに位置し易い元素Mを含む。元素Lは、少なくともZrを含む。アルカリ電解液は、4.6mol/L以上の濃度のNaOHを含む。
