Title (EN) LEAD STORAGE CELL
(FR) ACCUMULATEUR AU PLOMB
(JA) 鉛蓄電池
Abstract:
(EN) A lead storage cell comprises a positive electrode plate, a current collector, and a negative electrode plate having a negative electrode material supported in the current collector. The negative electrode material contains fibers at a ratio of 0.05-0.40% by mass. The average length of the fiber is 1-6 mm, and the average volume-specific resistance value of the fibers is at least 103Ω·cm and less than 109Ω·cm.
(FR) La présente invention concerne un accumulateur au plomb qui comprend une plaque d'électrode positive, un collecteur de courant et une plaque d'électrode négative comportant un matériau d'électrode négative soutenu dans le collecteur de courant. Le matériau d'électrode négative contient des fibres à un rapport de 0,05 à 0,40 % en masse. La longueur moyenne de la fibre est de 1 à 6 mm, et la valeur de résistance spécifique en volume moyenne des fibres est d'au moins 103Ω·cm et inférieure à 109Ω·cm.
(JA) 鉛蓄電池は、正極板と、集電体と集電体に支持された負極材料とを有する負極板と、を備える。負極材料は、0.05質量%以上、0.40質量%以下の割合で繊維を含有している。繊維の平均長さは、1mm以上、6mm以下であり、繊維の平均体積固有抵抗値は、10Ω・cm以上、10Ω・cm未満である。
