Title (EN) LEAD ACID STORAGE BATTERY
(FR) BATTERIE DE STOCKAGE AU PLOMB-ACIDE
(JA) 鉛蓄電池
Abstract:
(EN) [Solution] This lead acid storage battery is provided with a negative electrode plate and a positive electrode plate. The negative electrode plate contains a negative electrode material that contains a carbon material and barium sulfate. The carbon material contains a first carbon material that has a particle diameter of 32 μm or more and a second carbon material that has a particle diameter of less than 32 μm; and the ratio of the powder resistance R2 of the second carbon material to the powder resistance R1 of the first carbon material, namely R2/R1 is more than 15 but less than 230. The content of the barium sulfate in the negative electrode material is from 0.2% by mass to 0.7% by mass (inclusive). The density of the negative electrode material is 3.8 g/cm3 or more.
(FR) La solution selon l'invention porte sur une batterie de stockage au plomb-acide qui comprend une plaque d'électrode négative et une plaque d'électrode positive. La plaque d'électrode négative contient un matériau d'électrode négative qui contient un matériau carboné et du sulfate de baryum. Le matériau carboné contient un premier matériau carboné qui a un diamètre de particule supérieur ou égal à 32 µm et un second matériau carboné qui a un diamètre de particule inférieur à 32 µm; et le rapport de la résistance à la poudre R2 du second matériau carboné à la résistance à la poudre R1 du premier matériau carboné, à savoir R2/R1 est supérieur à 15 mais inférieur à 230. La teneur en sulfate de baryum dans le materiau d’électrode négative est de 0,2 % en masse à 0,7 % en masse (inclus). La densité du matériau d'électrode négative est supérieure ou égale à 3,8 g/cm3.
(JA) 【解決手段】鉛蓄電池は、負極板と、正極板と、を備える。前記負極板は、炭素材料と硫酸バリウムとを含有する負極電極材料を含む。前記炭素材料は、32μm以上の粒子径を有する第1炭素材料と、32μm未満の粒子径を有する第2炭素材料と、を含み、前記第1炭素材料の粉体抵抗R1に対する、前記第2炭素材料の粉体抵抗R2の比:R2/R1が15を超え230未満である。前記負極電極材料中の硫酸バリウムの含有量は、0.2質量%以上0.7質量%以下である。前記負極電極材料の密度は、3.8g/cm3以上 である。
